And I guess we can now close the bug.

Thanks.

P.S.  Was the last change pushed?  I don't see it on the release
branch.

[Message part 4 (text/plain, inline)]

Emacs from git crashes on next code:

  (require 'xwidget)
  (with-temp-buffer
    (xwidget-insert (point-min) 'webkit (buffer-name) 320 240))

I know about at least one character required to attach text property to it,
however I think elisp code should not crash the Emacs

Thanks
