Improve accessibility of admin toolbar when zooming

[EWashb]

Background

Still an issue in D10

Currently, the admin toolbar becomes vertical instead of horizontal when zooming. Up to 200%, there is not much of a concern, but zooming further in causes the toolbar to overlap the main content section and the display cannot be seen.

Example of 250% zoom:

Accessibility Standard

WCAG version 2.1 AA, Criterion 1.4.10

Acceptance Criteria

• tech review of admin toolbar options
• consideration given at different levels of zoom
• UX review

There is current work to update the admin toolbar module. This would make the default layout vertical rather than horizontal and may resolve some of the issues we are currently seeing. It may be beneficial to wait on this ticket until the D.o work is completed.

@EWashb I don't think this is an issue we need to fix. As the user can choose to close the admin toolbar with the "manage" hamburger button at the top to see the content and thus doesn't need to scroll to see the content, this does meet WCAG 2.2 SC 1.4.10. That along with Drupal looking at updating to a vertical only toolbar, I think this can be closed.
