`webdriver.bidi.session.new` - multiple sessions should have a behavioral subfeature

[ddbeck]

What type of issue is this?

Missing compatibility data

What information was incorrect, unhelpful, or incomplete?

The MDN page talks about multiple sessions and their support:

In browsers that don't support multiple sessions (e.g., Firefox), sending session.new when a session is already active results in an error response […]

The compat table doesn't reflect this.

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Browser), Firefox

What did you expect to see?

A subfeature showing whether a browser can support multiple sessions with WebDriver BiDi.

Did you test this? If so, how?

#29972 dropped the note about multiple sessions. The linked bug, https://bugzil.la/1862018, is still open.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

A subfeature showing whether a browser can support multiple sessions with WebDriver BiDi.

Support for multiple sessions is already captured in the WebDriver BiDi Implementation Status spreadsheet, but no browser appears to support it, so no BCD feature is generated as part of the sync.
