Hello,
I’m also interested for a solution for that problem.
For me the workaround is to use auto type. You can add a custom target window
or a matching URL with the WebAutoType Addon ( https://sourceforge.net/projects/webautotype/ ) using the global auto type shortcut.

But this isn’t as comfortable as the Kee addon.
Kind Regards.
