Epic #89595: Improve accessibility of backend
Tooltips in Backend should become accessible
The title attribute is not sufficient for an accessible tooltip. There are screenreaders that do not announce the title attribute and also users of mobile devices have not chance to see the tooltip.
It would be nice to have a new globally available tooltip option that is accessible and can be used in cases where currently title attributes or other alternatives are used.

When having a look at the WAI-ARIA practices it shows they are still "work in progresss" https://www.w3.org/TR/wai-aria-practices-1.1/#tooltip
But there is other (more informative) information on accessible tooltips on the following two pages:
The most important things are:
- do not rely on the title attribute, that is not sufficient (and not usable on mobile devices at all)
- use aria-describedby to identify the tooltip for the element the tooltip is attached to
- use role="tooltip" for the tooltip itself
- tooltips should appear on focus as well as on hover
