Description

This is a request for a WebKit standards position on the idea of adding (optional) light dismiss functionality to Dialogs.
See whatwg/html#9373 for the discussion. The current proposal is a new attribute closedby (naming TBD) with three values allowing no close bahaviour, close watcher behaviour, or close watcher and light dismiss behaviour.

Draft PR to give a rough idea of what this could look like whatwg/html#10157

It's rather unclear what the actual state of this proposal is. I take it whatwg/html#9373 (comment) is the current proposal still? I don't understand how people are now comfortable with changing the default. How does that reconcile with whatwg/html#9373 (comment)?

And if Esc somehow already closes dialogs or soon will be capable of closing all existing dialogs, why would we add a way to declaratively disable that again?

[lukewarlow]

To clarify the default will be the existing behaviour. No change will happen until you add the attribute with a specific value. In html terms the missing value state will be an "auto" state with no corresponding keyword.

whatwg/html#10157 - here's a rought draft PR.

I will take a look at the stacking stuff not familiar enough to answer.

As for why to offer a way to disable it, well we need the mechanism to match existing behaviour for non-modal dialogs, and we may as well allow that for modal dialogs too? I believe Domenic may have mentioned that it's come up as a feature request too.
