liferea sometimes displays images too large

[Jim Bauer]

When viewing feeds that have large images, the images are not scaled down to fit into the window like browsers typically do.

To reproduce:
- add feed like https://www.monkeyuser.com/feed.xml that has lots of large images
- make sure your liferea window isn't too wide (width of about 1000px should be good)
- view most any item in that feed (I was using the one dated Aug 2)
- see that the image extends beyond the content pane thus adding a horizontal scroll bar

I expected that the image width to be scaled to fit into current content pane. This was happening in a earlier version (Ubuntu 20.10 I believe)

I tried an old workaround from https://www.keypressure.com/blog/shrink-liferea-images/ that said to add the following to ~/.config/liferea/liferea.css

div.content img {
    max-width: 100%;
    height: auto;
}

That did not work.

I also tried adding the --debug-html to liferea to have it save the generated html in ~/.cache/liferea/output.html and then viewed that in a web browser (firefox). The image was scaled as expected there (with or without the above mentioned liferea.css change). Furthermore, changing the max-with to something like 50% the browser showed the change when viewing the output.html file, but liferea always just displayed the image at full size.

For what it's worth, I'm not seeing this behavior with 1.13.6-1 for Debian experimental. It could very well be that this is due to the webkit2gtk update, which we have a patch for in 1.13.5-2.

Is there a way I can try out 1.13.5-2 on Ubuntu 21.04?

Upgraded to Ubuntu 21.10 yesterday and noticed today that the issue with the overly large images is not happening anymore.

Working ok with or without the above mentioned change to .config/liferea/liferea.css
(BTW if I modify that change with 'max-width: 50%' the image width does shrink in half)
