Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. I can’t reproduce this issue. Could you please update to version 2.1.39 and check if the issue persists?

I just updated, yet the popover still renders below the suggestions, and also no longer correctly placed next to the lines marked, but e.g. offset. see my highlighted text that triggered the popover to appear, and where the “Add to chat” popover is actually rendered.

.cursorHoverWidget has a z-index of 100000

.removed-lines-zone-widget has a z-index of 10
.inline-diff-removed has a z-index of 1

the z-index has no effect, as the cursorHoverWidget is not in e.g. toplayer and on a lower level in the DOM.

removals are part of overlayWidgets
but additions are part of view-overlays
