Description

When selecting a portion of code, the “Chat” and “Edit” floating buttons appear as expected.
However, when scrolling down, the code located below the floating buttons does not scroll in sync with the rest of the editor content above the buttons.

This creates a visible graphical desynchronization where part of the code appears visually “stuck” or offset while the rest of the editor scrolls normally.

To reproduce

1. Select 2–3 lines of code in the editor
2. Ensure the floating “Chat” and “Edit” buttons are visible
3. Scroll down vertically in the editor
4. Observe that the code below the floating buttons does not scroll in sync with the rest of the content

Log output

No error visible either in JCEF DevTools console logs or Continue log file :

We've traced this issue to the 'Chat, Edit' tooltip.

As a workaround, clicking anywhere in the editor will cancel the code selection and the display will return to normal.
