System Information

• Extension Version: Version2.2.0
• App Version:
• Browser and Version: Edge, Version 96.0.1054.34 (Official build) beta (64-bit)
• Client OS and Version: Ubuntu Linux

Steps to reproduce

1. Open Zyxel T50 modem-router admin page
2. Add static dhcp lease
3. Error is displayed in console, also unable to add static dhcp lease

Expected result

It should work.

Actual result

My modem-router shows an error dialog, about being unable to store the static dhcp lease.
In the console i see an error:

       Uncaught TypeError: t.querySelectorAll is not a function
    at o.getPasswordFields (client.js:formatted:62285)
    at MutationObserver.<anonymous> (client.js:formatted:62679)

When debugging i see that this piece of code is hit multiple times. Most of the times "t" is of type "document". When an error is thrown, then "t" is of type "comment".
let e = t.querySelectorAll('input[type="password"]')

Browser log

   Uncaught TypeError: t.querySelectorAll is not a function
at o.getPasswordFields (client.js:formatted:62285)
at MutationObserver.<anonymous> (client.js:formatted:62679)
