Debugger scenario fails on small screens

[krassowski]

Description

The bug icon is not visible on small screens as it gets collapsed into the responsive scrollbar. This prevents CI integration (krassowski/benchmarks#2):

    Error: proxy.evaluate: Selector button[aria-disabled="false"][title="Disable Debugger"] not found in attached state in 5s

Unfortunately there is no enable/disable command for debugger (jupyterlab/jupyterlab#14463)

Another part of the problem is that the test notebooks gets always opened in split-right mode:

Expected behavior

Debugger scenario works regardless.

Context

• JupyterLab version: 4.0.0rc0
