Outdated picture does not get updated
I encountered a strange behaviour, which doesn't seem right to me, as follows:
- I load a webpage with a picture
- I right-click onto the picture and "Open image in new tab". The picture is shown in the new tab.
- I replace the picture on the server
- I reload the first tab. It correctly shows the new picture now.
- I go to the second tab again. It still shows the old picture (so far that is obvious and expected)
- I reload the second tab. It does *NOT* update the picture!
Retrying this with Developer/Network opened on the second tab shows the size of the *NEW* picture and "cached". (304 Not Modified) That would be correct (because the picture was already downloaded in the first tab), but I might suppose the page shoud then change to the new picture.
When I engage the "Disable Cache" checbox in the Developer, things work as expected - but that seems quite obvious.
This is FF 128.6.0esr, built for FreeBSD 13.4
Cross-Check: chromium also reports 304 Not Modified, but does update the picture in the second tab on reload.
