Bootstrap 4 issues and 3.0 release

[trollfot]

Hello.
Recently efforts have been put into having a bs5 version ready.
On the roadmap to 3.0, a lot of errors are marked as BS4.
As we are very keen on seeing a new version 3.0 released, is it possible to tour the issues and close or bump them, so we could help tackling what is remaining ?

I renamed the BS4 label to BS5. We will skip BS4 entirely in the upcoming 3.0.0a release. I expect to have time this week to make a release. 🤞

I think that most, if not all, of these issues are still relevant in for BS5.
