TYPO3 Core

Use polite live region and announce "Checkbox page read also checked" and respective "Checkbox page write also not checked".

For the toggle options the announcement would be "All read checkboxes also checked" and respective "All write checkboxes also not checked".

Hints:
- the live region must be emptied after a timeout to allow announcing the same value again for the next checkbox. This needs to have a timeout (see code below)
- assistive technologies use "not checked" instead of "unchecked" because the announcement is easier to recognize.

document.getElementById('liveregion').innerText='Checkbox page read also checked';
setTimeout(()=>{document.getElementById('liveregion').innerText='';},500);
