Greptile Summary

This PR adds display: block !important to the .list.collapsible.hidden rule in list.scss, preventing plugin stylesheets that target .hidden from fully hiding the collapsible container in the sidebar.

• The new !important declaration wins over a plugin's display: none !important on .hidden because the three-class selector (.list.collapsible.hidden, specificity 0,3,0) outweighs a plain .hidden rule (specificity 0,1,0) — CSS specificity still governs competing !important declarations within the same origin.
• The icon-content overrides (.folder::before, .indicator::before) already used !important; the container's display declaration is now consistent with that pattern.

Confidence Score: 5/5

Single-line CSS addition that restores container visibility against plugin overrides; no JavaScript, no logic, no regressions expected.

The change is a one-line addition to a well-scoped CSS block. The three-class selector gives it enough specificity to win over typical plugin .hidden overrides even when both sides use !important. No other files are touched and the fix is self-contained.

No files require special attention.

Important Files Changed

Filename	Overview
src/styles/list.scss	Adds display: block !important to .list.collapsible.hidden so that plugin stylesheets targeting .hidden cannot fully hide the collapsible container; the collapsed child ul still uses display: none without !important.
