Cllipboard manager widget + Excel online = Bug City

Describe the bug
Has anyone ever experienced the clipboard manager widget of the touchbar while using Excel Online?
When I do this, many odd things happen:
When I copy a cell, 2 entries on the touchbar pop up instead of one. Sometimes they return the displayed text (and even the correct cell formating). But sometimes they all return the same text, this is especially broken when I mark entries as favorites.
And then there comes a point where my whole touchpad just freezes and I have to restart BTT.
Meanwhile, my alfred clipboard is still working fine.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touch Bar

Device information:

  • Type of Mac: MacBook Pro (15-inch, 2018)
    macOS version: OSX 10.15.1
  • BetterTouchTool version: (3.207)
