Number of glitches

[R-OLE]

On Win10:

1. Can get iframe to work at all.
2. Clicking on "bookmarks" icon after clicking on other icons can generate a second sub-window filled with bookmarks. After that, it can get snarled up and the sub-windows will disappear and nothing is visiable.
3. Using sidebar in a window causes problems with "MRU" tools - "Most Recently Used" tab order switching. I'm guessing Sidebar+ steals focus somehow and causes the tab switching to have nothing to switch between (Using QuicKey, with AHK helper per their github website).

Congrats on new extension. And Good Luck to you!
