📝 Summary
Moodle tooltips are not read aloud by screenreaders. Presumably this is down to the implementation of these tooltips specifically through Moodle, alongside the aria attributes not quite confirming to accessibility standards allowing them to be read aloud.

🎬 Steps to Reproduce
Enable a screenreader ([example chrome extension|https://chrome.google.com/webstore/detail/screen-reader/kgejglhpjiefppelpmljglcjbhoiplfn/related)] and navigate to any Moodle page containing a Moodle tooltip. For instance inside an assignment activity settings page there are many Moodle tooltips.

✔️ Expected Behaviour
When a user using a screenreader tabs to a tooltip, the text itself that's revealed should also be read out loud.

📓 Additional Details
I've been down an accessibility rabbit hole looking at this (non-developer here). Does this not break WCAG AA 2.1 accessibility criteria? (Unsure on which criterion point exactly though...). Would tooltips in Moodle need ot be re-implemented or is there a way of adding aria attributes to resolve this like aria-live or aria titles?
