Limitations

• These are experimental features

  • Input Element blurring
  • Tab title masking

• The following HTML elements are not supported:

  • HTML Canvas
  • TextArea

• Web Terminal based on Xterm.js:
  see here

• Web Editor based on CodeMirror:
  CodeMirror, which bases GitHub code editor, repairs its own contents automatically after blurring by this extension. Then blurring and repairing are repeated, it causes infinity loop. (#62)

  [!NOTE] Not limited to CodeMirror, it's possible that an infinity loop and a site freezing happen caused by repeat of blurring and DOM tree keeping when the extension tries to blur text on a site composited by frameworks or components which try to keep DOM tree. As long as I investigate, lexical is also such a component.

Dependencies

• jsdiff: A JavaScript text differencing implementation (BSD 3-Clause License).
