Chrome and Safari either disable this or handle it badly. We don't handle it great so disable it.
Although the document principal looks like it can change I think if that happened at minimum the presshell would be recreated, which creates the ZoomConstraintsClient so we shouldn't need to register to be notified if this changes.
The other option would be to implement support for prevent default of double taps and then have modify pdf.js (if it doesn't already prevent default ctrl wheel events).

This is verified fixed using Firefox 89.0a1 (BuildId:20210323094659) on macOS 10.14 & 11.1. The double-tap to zoom functionality is no longer available inside print preview.
