Fixed Settings Sidebar Scroll Issue in Page Editor (#5528external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

In the page editor’s settings sidebar (Element / Style tabs), long forms couldn’t be scrolled to the bottom — the last fields were cut off and unreachable. This was caused by hardcoded height calculations that didn’t account for varying chrome heights above the sidebar. The sidebar now sizes itself dynamically from its top edge to the viewport bottom, ensuring all form fields are always accessible.

Fixed Long File Names Overflowing the Style Panel Sidebar (#5522external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

In the page editor’s Style panel, selecting a background image with a long file name (e.g. a hashed name like clouds-128082585-e37ab6...-long-hash.jpeg) would overflow the sidebar row and push the Edit/Remove buttons off-screen. The sidebar now truncates long values with an ellipsis, keeping all action buttons visible.

Fixed Background Image Showing Generic File Icon Instead of Thumbnail (#5522external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

The Background → Image picker in the Style panel displayed a generic file icon instead of the actual image thumbnail. This was a display-only issue caused by a data shape mismatch — existing pages are unaffected and the thumbnail now renders correctly.

Fixed Page Translation Failing for Integration-Created Pages (#5535external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

Translating a page that was created via an integration (and lacked a language property) would fail with a validation error. The translate action now handles pages without a language property, allowing them to be translated normally.

Fixed DataTable Columns Menu Closing on Single Selection (#5518external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

The columns visibility menu in DataTable components closed immediately after toggling a single checkbox, preventing you from showing or hiding multiple columns in one session. The menu now stays open until you click outside it, allowing multi-select.

Fixed DataTable Columns Cog Not Staying Flush Right (#5518external link)
anchor

{/ REVIEW-PENDING @adrians5j — confirm this entry, then delete this line /}

When hiding columns in a DataTable, the settings cog icon would drift leftward as the table no longer filled its container width. Resizable columns now absorb the space left by hidden fixed columns, keeping the table at full width and the cog pinned to the right edge.
