(Webkit) Graph view: clock-face progress indicator missing

[MetRonnie]

I spotted one issue where the clock-face progress indicator doesn't show in the graph view:

I think this was working before [Vue 3] but I remember there was some difference between Safari/others regards SVG rotation-centre coordinates. Working on other browsers?

This is Safari only?

[oliver-sanders]

WebKit is the rendering engine used by Safari and some others on MacOS and all browsers on iOS (incl Chrome).

It's also used by some minor browsers but we don't need to worry about those.

Was this fixed by #1780?

I think I tested this with Safari, but I can't confirm it.

Working well on Safari!
