This PR makes the ligtness of disabled buttons fixed. Disabled buttons should fade into the background , so the lightness has to change depending on which background a button is put on. So this does not close the mentioned issue.

@Riyazul555 There is already an open PR for the issue. Please see https://github.com/twbs/bootstrap/pull/40559 – feedback welcome!
