📝 WalkthroughWalkthroughThe admin builder initializes a shared hover pill for field-list buttons. The module handles hover, leave, and drag interactions. SCSS styles the pill, button layering, animation, and reduced-motion behavior. ChangesField list hover pill
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The Add Fields hover animation can retain the old button highlight instead of the shared pill, and longer pill movements can stop dimming prematurely while moving within a button. These visible interaction regressions should be corrected before merge. Sequence Diagram(s)sequenceDiagram

Increase the hover override selector specificity.
Line 288 cannot override the fallback rule at lines 83-90. The fallback selector includes #frm-insert-fields, so it has higher specificity. The button keeps its white background and shadow when the shared pill is active.

Each button faded in its own background, so nothing carried the eye between them. One element per list now travels to the hovered button, with travel time scaled to distance so a fast sweep neither lags behind nor stays dimmed. Basic, Pricing and Advanced are separate lists, so each gets its own pill; positions are measured against the list the button sits in.

This branch had downgraded it to string concatenation, which oxlint's prefer-template rejects. Reverting to master's version removes the change from the diff entirely.

Ignore descendant-to-descendant mouseover events.
When the pointer moves inside the same button, mouseover calls moveTo() again with zero distance. Line 113 then calls settle() and removes dimming while a previous long transform transition is still active.
Proposed fix
list.addEventListener( 'mouseover', event => {
const button = event.target.closest( 'li.frmbutton > a' );
if ( ! button || button.classList.contains( 'disabled' ) ) {
hide();
return;
}
+
+ if ( event.relatedTarget?.closest?.( 'li.frmbutton > a' ) === button ) {
+ return;

moveTo( button );
