What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

• It says Firefox does not support the feature at all
• It says Chrome supports the feature since 88

What browsers does this problem apply to, if applicable?

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

What did you expect to see?

• Firefox supports this feature from version 123: https://phabricator.services.mozilla.com/D196856
• Chrome supports the feature but only as the HTTP header and not when used in the allow directive of an iframe: https://chromestatus.com/feature/5175677674586112

Did you test this? If so, how?

• Tested the Firefox change by adding a unit test to the change
• Didn't test Chrome but linked the docs in the previous question

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

Edge is probably the same as Chrome
