Preview not working when VSCode is idle for a while

[mozhewen]

Describe the bug
When VSCode is left idle in the backstage or the machine is asleep for a while,
the existing Preview tab will stop updating upon resumption.
The only solution so far is to close the tab and open a new one.

Package/Software version:

System: MacBook Pro 2021, macOS: 15.2 (24C101).
VSCode version: 1.97.2.
tinymist extension version: v0.12.18.

I've also noticed this happens much more quickly (even while still editing VSCode), when using a main file and multiple #includes.
