Three new patches extending workbench font customization to all areas:
- feat-workbench-zz-area-font-family: fontFamily for sidebar, statusbar,
tabs, panel, activitybar + global fontSize setting
- feat-workbench-zz-area-font-size-core: fontSize for statusbar,
activitybar, panel with proportional scaling via FONT object
- feat-workbench-zz-area-font-size-tabs: fontSize for tabs with CSS
variable scaling for tab heights and widths
Includes fixes from audit review:
- Fix stale CSS var when fontSize reverts to default (cache isUserSet)
- Fix else-if config listener blocking simultaneous updates
- Trigger grid relayout after statusbar font-size change
- Apply activitybar font before show() for correct initial sizing
- Trigger tab relayout after font-size change
- Standardize CSS fallback chains to include global font-size
- Extract inspectFontSize() helper to reduce duplication
- Replace magic 1.833333 ratio with explicit CSS height variable
- Fix CSS variable name mismatch in auxiliaryBarPart.css
(was reading --vscode-workbench-secondary-sidebar-font-size
while TS sets --vscode-workbench-sidebar-font-size)
- Add line-height and title h2 scaling for auxiliary bar
- Add composite bar tab font size scaling (paneCompositePart.css)
- Update setting description to reflect both sidebars
Add two new workbench settings for controlling font sizes in sidebars:
- workbench.sideBar.fontSize: Controls primary sidebar font size (6-32px)
- workbench.secondarySideBar.fontSize: Controls secondary sidebar font size
This improves accessibility by allowing users to independently scale sidebar
content without requiring full UI zoom or source code edits.
Implementation uses CSS custom properties for live updates without reload.
Default of 13px preserves existing behavior.
