Firefox restyled Linux menupopups at some point to no longer conform to
the DE defined styles for GTK widgets. This removes that custom firefox
styling and uses DE defined values instead. This is especially apparent
on Linux Unity where menupopups are dark in both light and dark themes
by default for apps.
Reasoning:
- Different Linux DEs specify different titlebar button (min, max,
close) locations which we did not and could not support before.
- Previous approach copied from Firefox depended on custom offsets
specified in CSS instead of allowing the browser engine to place
elements
Changes:
- Titlebar and menubar no longer collapsed into each other with a
negative margin, instead just a single flexbox (on macOS the titlebar
is still collapsed into the tab bar)
- Support for -moz-gtk-csd-reversed-placement to correctly place the
titlebar buttons on Linux
- Removed/changed some code copied from Firefox that does not apply or
uses the wrong selectors
- Fixed the display of Linux Unity DE buttons with icons appearing outside
of button borders
- Removed the Z in the titlebar on Linux since only a few DEs use that.
- Aligned the tabbar on Linux and Windows to the left margin of the
window.
- handle space and enter in zotero pane to always click on toolbarbutton.
It ensures consistent behavior across all components to avoid Enter
triggering click on some buttons but not others.
- address the issue of focus not being able to leave the reader once it
gets there. On Escape, when reader is opened, instead of re-focusing the reader,
focus the selected tab. From there, Enter will focus the reader, and tabbing
allows you to reach the itemPane.
- Tab/Shift-tab moves focus between Sync button and itemPane when
reader is opened
- min/max-lines attribute on editable-text determines how tall the field
can/has to be
- if max-lines is not specified (or is below 1), the textarea will expand
as much as needed without overflow
- removed hardcoded height and variables from css, substituted them with
usage of these attributes for consistency
- No fields have any max-lines at this point, so all fields will expand as
needed
- Added tooltip to display the entire title of the tab on hover
- Ellipsize the text of the tab title to display as much of the last
word as possible
Fixes: #3609
- right/left arrows on section header expand/collapse the sections
- space/enter on section header toggle section collapsed/expanded
- tab from the header goes through the header's buttons and then
tabs into the section if that's opened
- arrow up/down on the header jumps to the previous/next header
- space/enter on clickable elements simulate a click
- if there is a pinned section, tab from the title will focus its header
