Subject: [PATCH] Set role=button on TOC show/hide checkbox

This should give more intuitive hints in assistive technology,
identical (or similar) to the hints for the JavaScript-generated
button we had before 68527cf47935a0350d3f0a153bd06cbb98062ec8.
See results of testing with Windows Narrator/VoiceOver: T195053#4428563.
