[BUG] VSCode: opening a plugin resizes entire application.

Jdaviz component

Cubeviz

Description

Follow up from #3309, something I noticed when testing that is that when running in VSCode, opening a plugin causes the whole application to resize to be large enough to display the entire plugin, rather than having a scrollbar:

Here's another video that shows related behavior:

• Each additional plugin opened in the sidecar will cause increase in height for all viewers
• Also, toggling the sidecar off will close both the sidecar and all viewers

Unrelated to this issue, I have seen both the expected icons displaying correctly throughout the app and how they display in this video below (I made some changes to my local environment but haven't pinpointed what causes the display bug).
