Research direction
The issue is about Apple Pencil input producing hover instead of click. Look at the event handling code in the Theia frontend, specifically in packages/core/src/browser where pointer events are processed. Check the touch event listeners and how they differentiate between hover and click. The expected behavior is that a short tap should trigger a click action. Investigate if there is a missing touch to click conversion or a conditional that incorrectly filters out such events. No linked PRs or comments provide further hints.
