Keyboard-only users (ambulatory), do not see the hoverable/tooltip of the icons in heading and in code cells when focusing on the elements.

Issue Area # 3

• Expectation: Is content that appears on hover or keyboard focus dismissible, hovberable, and persistent? (WCAG Criteria 1.4.13 (AA))
• Observed:
  • All hoverables (tooltips) are not appearing on keyboard focus based on what I could tell. AKA, people using only keyboard do not know that the play button in the heading has meaning "Run the selected cells (Shift + Enter)". They just have to guess what all of these buttons do.

@manfromjupyter i can confirm that keyboard focus does not show the tools tips.

Display the title attribute on focus indicates that this behavior requires javascript to be implemented.

i imagine there are a few folks that have the chops to land this.

Title should appear on keyboard focus in JupyterLab as well

I have a play with the CSS-only version, and it looks weird, I guess it needs to go down the js route?

One more question, it seems the ui-component is from a JupyterLab library. Maybe fixing one will fix both? (I am not sure, just asking)

we suspect that a lot of notebook fixes will also be jupyterlab fixes since notebook uses jupyterlab components.
