"Terminal" UI not rendering properly on Safari (Mac OS)

[nickdos]

Problem/Motivation

Apple recently did a major version number release of Safari on Mac OS (version 15.0) and since running that update I've not been able to use the Terminal/SSH UI in Home Assistant. The add-on appears to load as expected but no text is rendered in the UI. See screenshot below:

Using a different browser, the UI loads as expected, so I suspect Safari update is the issue.

I posted this in the HA forum and another user has confirmed they see the same thing as me.

Expected behavior

I expect to see the SSH UI renders with text, including the terminal prompt, etc.

Actual behavior

I only see the coloured background and blue bar along the bottom, as well as a single white square that moves if I type or click the mouse (randomly). Screenshot included above.

Note: I checked for JS errors in the browser console and there were no errors or warning reported.

Steps to reproduce

Run HA via Safari version 15.0 or later on Mac OS 11.6 or later
