Description
## Description
Similar to switching tabs (https://github.com/jupyterlab/jupyterlab/issues/4292) and opening notebooks, closing notebooks is slow.

Open a notebook with 1k cells.
The performance graph looks like this when closing it (all the purple at the bottom is another forced reflow):
## Expected behavior
It closes even faster than it opens
## Context
- Operating System and version: Linux
