Steps to reproduce:

  1. Open NVDA
  2. Open Edge Chromium browser
  3. In NVDA advanced settings, set UIA for chromium browsers wo "yes"
  4. Open a website with text paragraphs, I used a german news website:
    www.ntv.de
  5. navigate to the end of the virtual document with ctrl+end press p, or just press p until no next paragraph is found.

Actual behavior:

NVDA freezes for at least 45 seconds for every key press.

@mltony can you look into this as well? UIA in browsers is not fully mature yet but if someone uses it and presses p accidentally when next paragraph can be found, the user ends up with its keyboard frozen for several minutes. Quite severe issue in my view because p is assigned by default.
