});

Reproduction Steps

Actual (Problematic) Behavior

I see a console error:

dom.ts:462 Uncaught TypeError: Cannot read properties of null (reading 'getBoundingClientRect')
    at Object.O [as getDomNodePagePosition] (dom.ts:462:21)
    at u.doLayout (contextview.ts:324:33)

Expected Behavior

The context menu would pop open

Additional Context

I can also reproduce this on a minimal creation of the code editor in React and Vite.

Notice how the context menu does not seem to be styled.

Please note that also happens when right clicking on the deleted line.

In 0.34.1 the menu still had a correct background:

In VS Code it's fine:
