Add note about pointer activation and roving tabindex/aria-activedescendant

[patrickhlauke]

Adds a new note advising authors to also change the roving tabindex / set the correct aria-activedescendant reference as a result of pointer interactions (clicks, taps, ...) as otherwise there will be a mismatch for users that navigate with both keyboard and pointer.

Also adds <code> ... </code> around relevant words like tabindex and aria-activedescendant

Closes #1710
