I see. This is exactly the feature which does not help for my use case,
since it only resizes the tabs and not all the other tab fields, which I
would like to truncate.

I would like to see an option `tab-bar-truncate' or `tab-line-truncate'
which simply prevent line wrapping, similar to the buffer variable
`truncate-lines'.
