The same issue occurs with getDisplayMedia() which is potentially higher impact, becuase it means that MediaRecorder can't reliably record a window.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Recording' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Perhaps support for size changes would be classified as an enhancement, but the Restricted {} error property on the "error" event at least looks like a defect.

Reproduced when sharing a calc window application on Windows via getDisplayMedia api.
See https://jsfiddle.net/r3cwqhbn/3/
Cick Start button, select a window to share, then resize it
