Revert "Clarify the keyboard focus warning"
I think you're onto something here. However, ([tabindex]) should probably be concatenated with :not([tabindex="-1"]) ?
Well, that would be a further improvement to my change. I wouldn't go as far as to revert it. Perhaps even have a separate rule:
button[tabindex="-1"], a[tabindex="-1"], .btn[tabindex="-1"], .button[tabindex="-1"], input[tabindex="-1"] {
}
P.S. Mention a developer to invite him to join a discussion. I got to know about this pull request by accident.
@denis-sokolov like this? Yeah, sorry :-)
The trouble is tabindex="-1" is focusable programmatically. In some ARIA widgets, -1 on links or buttons is necessary for turning tabbing off before adding custom key controls like arrow keys (?)
Well, then just leave it as it is.
If somebody has explicitly chosen to add tabindex="-1", I don't think they need a warning about the element being unfocusable.
