Bug 234039 – Improve <type="datetime-local"> value parsing and sanitization

• Component: Forms
• Status: RESOLVED FIXED

[Chris Dumez]

Allow using a space as date / time separator in <type="datetime-local">, instead of simply allowing a 'T'. This would align our behavior with Gecko and allow us to pass more tests in WPT.

This comment does not make sense any more and should be deleted.

Specification allows a space or a 'T' (in line with WPT test):
https://html.spec.whatwg.org/multipage/common-microsyntaxes.html#valid-local-date-and-time-string

Will clarify the change log.

I guess I will need a more generic bug title.

Regression, not progression?

Weird, no such failure in the Mac output. I'll investigate.

Thanks for catching.

It was just a bad baseline because I had a patch impacting the same test that landed super recently. No issue with the code change itself.
