Support for Headers.get()

[o-alquimista]

According to these compatibility tables below, the Headers.get() method is not supported on Firefox for Android.

• https://developer.mozilla.org/en-US/docs/Web/API/Headers/get#browser_compatibility
• https://caniuse.com/mdn-api_headers_get

I'm setting up remote debugging to investigate the current status of this method. Do you know anything about it?

UPDATE:
Apparently, it works on the latest Firefox for Android (at the moment 91.3.0):

So the information on the compatibility tables is outdated. The question now is, when was the support for this method introduced?

UPDATE 2:
Issue opened for the MDN compat data: mdn/browser-compat-data#12102
