abbr[title] with tooltip is deleting dotted underline styling #39026

Describe the issue
I use a <abbr title="...">...</abbr> abbreviation in text.
This is good because it provides context for YTD and other terms that not everybody knows.
Now, because in 2023 every human-computer interaction that takes more than 10ms is broken, and because browsers typically take 1,000ms to show that abbreviation title, I use BS tooltips to show this abbreviation.
In this scenario, the tooltip will properly show on mouse-over. But now it is hiding the dotted underline styling that makes this feature discoverable.

This is an interesting use case.
Indeed, Bootstrap Tooltip JS will use
titleand replace it withdata-bs-original-title, and so the dotted default browser rendering will be broken because I suppose that<abbr>usestitleto make the dotted rendering. Even the accessibility will be probably broken because the title of an<abbr>is read by screen readers.Haven't tested it at all but you could maybe try something like this (kinda ugly) in the meantime (even if you'll probably have both tooltips: browser + Bootstrap):
