CK5: Button widths incorrect

Affected version: >=4.0.0-alpha12 < 4.0.0-alpha14, possibly earlier

Alpha 14 reverts changes from alpha 13, so it may not be affected

Also affecting the latest version. Provided a patch / MR with !124

@freezernick, I can't reproduce the issue on any instance. I suspect there is a conflict with a generic css class in your custom theme.

Could you please test again on the 4.x-dev branche and let me know?
