Epic #89595: Improve accessibility of backend
Pagetree Toolbar Focus Styles and Labels
Create new pages, Filter and Reload buttons have missing focus style¶
When you navigate with your keyboard to an interactive element, you should see a visible focus style. This success criterion helps to know which element has the keyboard focus. The Create new pages, Filter and Reload buttons don't change its style, when it receives focus.
Create new pages, Filter and Reload buttons have no descriptive text¶
When navigating to a button, a descriptive text must be presented to screen reader users to indicate the function of the button.
The Create new pages, Filter and Reload buttons use only the title attribute. Many user agents do not expose the title in an accessible manner as required by the specification (e.g. requiring a pointing device such as a mouse to cause a tooltip to appear, which excludes keyboard-only users and touch-only users, such as anyone with a modern phone or tablet).
