yatil marked as non substantive for IPR from ash-nazg.

[patrickhlauke]

Adding some context: this is for consistency with the normative wording of the SC, which uses "dismissible". In isolation, both spellings are correct AFAIK, but it's worth settling on one. LGTM

There's also one instance in wcag.json ... not sure if we want to touch that too?

wcag/guidelines/wcag.json

Line 3460 in 946397c

"Failure to make content dismissable without moving pointer hover or keyboard focus (Potential future technique)"

need to decide what to do with wcag.json

[yatil]

I saw the wcag.json, but I don’t know if it is actually used anywhere. I also don’t know if it is generated from somewhere else and would auto-update.

I now also changed wcag.json
