Zoom was Chromium's, not the application's: the web view handled the
keys natively and never told anyone, so there was no value to save.
qtmaildir now owns it. Zoom in, out and reset are real actions, in the
View menu and rebindable through [keys], and the factor is persisted to
the UI state file. Ctrl+wheel over the body zooms and Ctrl+middle-click
resets, both filtered by ancestry from an application-level filter: the
events are delivered to an internal QQuickWidget the web view creates
lazily, so a filter on the view itself never sees them.
The factor is clamped to 0.5 - 3.0, and NaN, infinity, zero and negative
values fall back to 1.0, since a corrupt state file must not be able to
leave the pane unreadable with no visible way back.
Both risks the plan flagged turned out not to exist, verified by probe
rather than assumed. The application QAction wins over the web view's
native zoom key, so the tracked factor cannot diverge from what is on
screen. And the factor survives setHtml(), so the web view is the single
source of truth and needs no reapply per render.
A third finding is worth recording because it produced a wrong fix
first. A probe using QTest::keyClick() reported Ctrl++ as a dead
binding, and a test was written asserting that. Both were wrong: Ctrl++
is exactly what the '+' key emits on an Italian layout, confirmed
against the real keyboard, and it is the shipped default. Whether a
symbol needs Shift is a property of the layout, not of Qt, and
keyClick() reproduces neither. The test now only checks that every
default parses, and the comment in defaultBindings() says not to
re-derive this from synthetic input.
Ctrl+= is a second binding for reset, skipped when [keys] gives it to
something else.
Also fixes a pre-existing bug the new config key exposed. [general]
entries were read as "general/<key>", which matches nothing: QSettings'
INI backend treats a section literally named [general] as its own
fallback section and strips the prefix. notmuch_config had therefore
never worked. Both keys are now read without it; the file format is
unchanged.

Clicking a thread left the pane blank. Two independent bugs, both from the
same false premise: that setHtml() navigates to the base URL it is given.
It does not. setHtml() navigates to a data: URL carrying the markup and
applies the base URL afterwards, purely as the document's origin. Verified
empirically on Qt 6.11.
Built on that wrong assumption were:
- MessagePage::acceptNavigationRequest compared the navigation's URL
against documentUrl() and rejected everything else, so the document load
was refused. It now accepts a typed main-frame navigation, which is one
we initiated ourselves.
- RequestInterceptor exempted exactly the qtmaildir: base URL and denied
everything else, so the data: document load was blocked too.
The interceptor fix is scoped to ResourceTypeMainFrame rather than allowing
the data: scheme outright. A blanket allow would have been a real hole: a
message body can write <img src="data:..."> or an iframe, and the existing
dataSchemeBlocked test in test_interceptor.cpp was right to fail when that
was tried. Sub-resource data: URLs remain denied.
Note this was never working. The drafted version had the same defect in a
different spelling (it compared url.scheme() rather than the whole URL, and
would have rejected the data: navigation just the same), and task 11 shipped
with no runtime test to catch it. test_messageview.cpp now pins all three
facts: the document loads, its text reaches the page, and a data: image
inside a hostile body stays blocked.
