Subject: feat: add onclose to MessagePort
|
|
|
|
|
|
|
|
|
|
This adds the 'onclose' event to MessagePort. This is
|
|
|
|
|
[proposed](https://github.com/w3ctag/design-reviews/issues/269#issuecomment-407584290)
|
|
|
|
|
in w3c and has been discussed for years without conclusion. I'd like to
|
|
|
|
|
get this standardised, but in lieu of that, this makes MessagePort a
|
|
|
|
|
whole bunch more useful!
