Description

Shouldn't be able to add 2 separate Bookmarks icons to Sidebar?

Steps to Reproduce

1. install 1.36.37
2. load brave://flags
3. set Enable Sidebar to Enabled
4. click RELAUNCH
5. click on the Bookmarks icon in Sidebar
6. context-click on a folder
7. choose Bookmark manager (brave://bookmarks)
8. hover on the + in Sidebar
9. choose bookmarks under Add to Sidebar

Actual result:

You now have two (2) Bookmarks icons in Sidebar (both work, but it's redundant). One opens the view in Sidebar; the other opens the Bookmarks Manager window proper.

Expected result:

Only 1? The original, smaller-sized icon?

Reproduces how often:

Brave version (brave://version info)

I don't know if this is actually a bug, now that I think about it. But the UX can be a little confusing here.
