Should we add more test cases: menu responsiveness, latex and moving tabs around #84
Description
Problem
jupyterlab/jupyterlab#9757 highlights some scenario where the entire UI becomes slow to respond due to a high number of DOM nodes.
Proposed Solution
Should we add test case for this scenario, or is it already somewhat covered by any of the existing benchmarks? Should we add a case for each non-covered manifestation of the problem (menu responsiveness, latex rendering, moving tabs around)?
Additional context
Tab switching is already covered (but it seems it has a different cause).
