I have reproduced this issue using Firefox 118.0a1 (2023.08.24) on Windows 10. I can confirm this issue is fixed, I verified using Firefox 118.0a1 latest nightly on Windows 10. Note that the inspect a svg element works only for the first time when accessing the test page, both when reproducing and verifying, see attached screenshots. On macOS and Ubuntu I am not able to inspect the svg image. Maybe this is another known issue?
