Intermittent Playwright test failures in theia-notebook-editor.test #14450
Description
I'm monitoring the stability of the Playwright tests and observed that there are a number of intermittent, recurring test failures at the theia-notebook-editor.test.ts.
Error: 1) ../../src/tests/theia-notebook-editor.test.ts:98:9 › Theia Notebook Editor interaction › should split cell
Error: elementHandle.waitForElementState: Element is not attached to the DOM
Call log:
- waiting for element to be visible

112 | const line = await cell.editor.lineByLineNumber(1);
> 113 | await line?.waitForElementState('visible');
| ^
114 | await line?.click();
115 | await line?.press('ArrowRight');

It is not alarmingly frequent, but it might be good to look into it anyway to avoid false-positives.
