Close dialog elements when the open attribute is removed #10124
Conversation
Fixes whatwg#5802 This patch adds attribute change steps to run the dialog closing steps whenever the open attribute is removed in order to prevent a bad state where the dialog is hidden but modal which renders the rest of the page inert.

This won't work, because it will return in step 1, because the open attribute has already been removed.
I guess we need to factor out steps 3-9 into a separate algorithm. Maybe "process open attribute removal"?

Whoops I forgot that, I added a parameter to close in chromium. I just added it here. What do you think?

I think it's slightly harder to understand than factoring out the steps would be, but I don't feel too strongly. (Thanks for updating the algorithm declaration style while you were there!)

Ok, I factored out the steps into a separate algorithm
I will ship this behind a flag, and I will let yall know if any issues come up. I don't have a usecounter for it but I don't see why this change would be a problem. |

Seems reasonable modulo web compatibility. @lukewarlow might also be interested in this. |

As a web developer (currently using <dialog> quite a bit), I'd be interested in seeing this change. (I've raised https://phabricator.services.mozilla.com/D201076 for Firefox).

(github doesn't seem to let me add comment in the right place outside the PR changes)
Don't "focusing steps" possibly end up firing an event at problematic time.

I think the best thing would either be to not focus the previously focused element in this case, or to post a task/microtask to focus that element. Thoughts? @domenic @keithamus

@dbaron too if you have thoughts

I'd prefer to schedule a task. We should avoid losing focus on the document if we can help it.

Scheduling a task sounds good to me too

@smaug---- what do you think of scheduling a task?

This feels like a big win for developers and having looked at the changes I don't think it's likely to cause any issues. Especially because it's unlikely developers will be relying on this behaviour (seems like its always undesirable) |
|
Any updates on this PR? It's mildly related to #10737 inasmuch as the close watcher logic is a little weirder (implementation-wise) when the open attribute can just be yanked off without calling close(). @josepharhar did you happen to try shipping the new behavior to see about web compat? (I'm happy to try, if there's consensus that this PR's behavior is desirable.) |
