Assigning this to @kswang1029, as it is primarily a user-facing thing. Most of the upgrades were fairly straightforward. I've removed deprecated code where possible.

@veggiesaurus not sure why but I am seeing e2e test failures due to changes of xpath (eg. the file filter text field). I will need more time to investigate this. And you are right about the color theme: the contrast is increased and the color theme appears less warm.

One issue: the initial file browser highlight box is squeezed.

@veggiesaurus @YuHsuan-Hwang there are a number of issues due to this library upgrade. I will summarize them in a google doc, just for better readability than posting here as a comment thread.
