[Bug] Button Click Takes Over 5 Seconds to Respond with Large Favorite List

[Kiddo-Kris]

Description of the Issue

I don't think this is a bug, but I think this is the most appropriate category for reporting this issue.

When viewing a large number of favorites, clicking anything, including favorites and sidebars, takes up to 5 seconds for VRCX to respond.

Steps to Reproduce

1. Go to the Favorites page.
2. Load a large number of favorites (~3500 items) (a test case with 1852 items is provided).
3. Click anywhere.
4. Measure the response time.

A DevTool profiler report for you to import into the DevTool profiler (with full 3500+ items) and a 1852-item test case are provided for testing:

• Profiler Report
• Test Case

Expected Behavior

VRCX should respond quickly, similar to other pages.

First thanks for your test case, I know there are big problems here, but I don't have many favs. This is an old problem from VRCX, so it's hard to make it respond very quickly. I can try to make it better, but it might require some time.
