Replace the click-only override with a WAI-ARIA disclosure navigation pattern so the docs version switcher is operable by mouse and keyboard. The previous hover disable also removed Material's :focus-within open path, so Tab never reached the list. The button now uses aria-expanded and aria-controls, the list is hidden until open, and Tab, arrows, Home/End, and Escape move through the real version links. Position the dropdown below the toggle so a second click closes it instead of activating a version, and lift the panel from the header.

Description
Follow-up to #2723. The click-only version selector could not be opened or operated with the keyboard because the hover override also disabled Material's
:focus-withinpath.This implements a WAI-ARIA disclosure navigation pattern (same class of control as MDN / many docs version switchers):
aria-expanded/aria-controls(noaria-haspopup)ul,hiddenwhen closed,aria-current="page"on the current versionTested by injecting the new CSS/JS into https://element.siemens.io/development/ (click, click-again, hover, Tab, arrows, Escape, ARIA, light/dark).
Backports to v49 and v48 are intentionally not included yet.
