1.13.4: Devtools open for frames instead of app://obsidian.md/index.html

Steps to reproduce

  1. In the sandbox vault, enable the web viewer plugin and open a web viewer tab
  2. Use mod-shift-I to open devtools
  3. The devtools are dev tools for the open web frame, rather than the app as a whole
  4. Close all tabs with web views (in the active window)
  5. Developer tools work again

Did you follow the troubleshooting guide? [Y/N]

Y

Expected result

Dev tools should open for the app, despite open web views (or other plugins using similar)

Actual result

If there is any web frame open, devtools open for that frame only.
