Steps:

The Test button has a tooltip with data-bs-html="true" on it and an <img> tag in the title. When you hover your mouse multiple times over the button, you will see that the the image in the tooltip will only be shown every other hover.

I tested this on Ubuntu 20.04 on Firefox and Chromium. It worked on 5.0 beta 1, the issue only started appearing after I upgraded to 5.0 beta 2.
