Describe the issue

I've tested the tooltips with NVDA on Chrome, Firefox and Edge (Windows 10) and with VoiceOver on Chrome and Safari: not all the tooltips I've in my project, and not always the same ones, are read.
It doesn't matter if I use the "title" or "data-bs-title" attribute in my HTML because evry time the results are instable and vary every time.

It's possible to replicate these bugs also in the documentation page https://getbootstrap.com/docs/5.3/components/tooltips/
