|Open||None||T31118 Add HTML 5 semantic elements 'details' and 'summary' to Sanitizer whitelist|
Updated bug summary & fields to clarify this is an enhancement request for supporting HTML 5 draft elements in wiki body text:
These would presumably be nice ways to implement various sorts of hidable sections, though user-agent support is likely to be lacking or inconsistent at this stage.
I would not recommend adding any explicit support at this stage, but it should be taken a look at some day.
Neat! We should probably confirm the behavior is consistent, predictable, and either falls back cleanly or can be emulated sanely (eg in IE 11 if it doesn't support it). Also double check that neither tag is used as an extension. Then I probably have no further objection. :)
I'm experimenting with this locally to see if we can replace mw-collapsible, polyfilling for IE11 and retaining the majority of the functionality for divs (while dropping tables and lists).
