Steam Web Browser Netflix does not WORK ANYMORE, PLEASE FIX

Steam Web Browser Netflix Error: M7121-1331-P7

This bug was introduced in the recent Steam Client beta that got pushed to the main Steam client last week. Prior to that, Netflix worked perfectly fine.

ISSUE
Attempting to watch Netflix in any ISteamHTMLSurface browser, such as in the Steam Overlay, now results in an on-screen error "Whoops, something went wrong... Unexpected Error Code: M7121-1331-P7"

OS
Windows 10

STEPS
Open a new web browser in the Steam Overlay.
Go to www.netflix.com
Log-in
Try to watch something

RESULTS
Instead of playing the video, the browser shows the in-page error message as described. Upon googling the error code, this Netflix page comes up saying it is a browser issue: https://help.netflix.com/en/node/61874

EXPECTED
For the video to play perfectly fine, as it did prior to the recent Steam client update.

NOTE
Other streaming sites, such as Curiosity Stream & YouTube, still work perfectly fine as before. The recent Steam client update only broke Netflix.
