The file-tree row tooltip says 'Double-click to rename' on every entry,
but folders don't actually rename on double-click — they navigate via
loadDir(). The tooltip is therefore misleading on directory rows.
Reported by @Deor in the WebUI Discord testers thread (May 5 2026):
'Ah that works yeah. May want to change the popup text as it also says
double click at the moment.'
Fix: gate the tooltip on item.type !== 'dir' so it only attaches to file
rows, where double-click does what the hint advertises. Folder rename
still reachable via the right-click context menu (unchanged).
Companion to #1698/#1702/#1707 — completes the rename-affordance triage:
- #1698 fixed: dblclick rename was unreachable on files (preview hijacked)
- #1707 fixed: single-click on filename did nothing (over-aggressive guard)
- #1710 (this PR): tooltip claimed dblclick-rename on folders too
Closes#1710
Tests: 4 source-level regression tests in tests/test_1710_folder_tooltip.py
guard the gate, the unchanged dir-dblclick navigate behaviour, the i18n key,
and that files still receive the tooltip. All 13 file-tree handler tests
(4 new + 9 from #1707) pass.
