Dark mode used to invert the whole message body with a CSS filter and
re-invert images and coloured cells. Brand colours came out shifted
(red turned pink), white cells set through bgcolor stayed white, and
the result changed after loading remote content because the blocker
strips the background attributes the selectors relied on.
The rendered body is now read back through computed styles and its
colours are rewritten in place: light backgrounds are darkened in their
own hue, vivid and dark fills stay as sent, text and borders only change
when they lack contrast, and anything painted on a background image is
left alone. Transparent dark images get their original light background
behind them when their pixels show they would vanish. The thread
conversation view uses the same pass.
Also fixed along the way:
- blocking remote content dropped every leading `<style>` block, so
mails lost their CSS until images were loaded
- a mail's `prefers-color-scheme` rules followed the OS instead of the
app theme
Cancelling an upload ended the loop like a normal finish, and the Files
app then reported every picked file as uploaded. Uploads now return how
many files went up and whether they were cancelled, so a cancel shows
"Upload canceled" (with the count of files that made it, if any).
Folder uploads also passed no cancel signal or progress callback to the
blob upload, so Cancel did not stop the file in flight and the progress
line stood still; they now behave like file uploads.
Uploads in Files had their own card with a thick progress bar, larger
corners and a heavier shadow, so they looked unlike the toasts around
them.
Toasts can now show work in progress: the thin line at the bottom fills
with progress instead of counting down, and the toast stays until it is
updated or removed. Uploads use it, with the file and percentage below
the title and Cancel as the toast action.
The image viewer only zoomed with its buttons, scaled the image inside
a fixed box so a zoomed image could not be moved, and the area around
the image swallowed clicks, so clicking beside it did nothing.
Both the Files image viewer and the attachment preview now use one
viewer that:
- zooms with the wheel, trackpad or two-finger pinch, centred on the
pointer, and with a zoom bar at the bottom (-, percentage, +, fit,
rotate)
- toggles between fit and full size on double-click or double-tap
- pans by dragging, or with the arrow keys, while zoomed
- closes on a click or tap beside the image, but not after a drag
- keeps + / - / 0 / r as shortcuts and Escape to close
