[Accessibility] Slide Viewer: Tooltip inaccessible on hover

[nwanduka]

Describe the bug
In the Annotation Assistant modal within the Preset Labels function of the Slide Viewer, the radius, threshold, and min overlap texts show a tooltip on hover. This tooltip can be dismissed and remains persistent, but it is not accessible via hover; it disappears upon hovering over it, making its content inaccessible to screen readers.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Slides'
2. Open a slide
3. Click on 'Present labels' icon
4. Go to 'Annotation assistant'
5. Hover over the texts "Radius", "Threshold", and "Min overlap". Notice that a tooltip appears.
6. Try to hover over the tooltip and notice the tooltip disappear on hover. This behavior makes the content of the tooltip inaccessible to screen readers.

Expected behavior
Content should not disappear on hover so that screen readers can access it.
