[elpaso]

Fixes #33682 (maybe)

Cherry-pick from master commit 72c0ae7

How can the "maybe" be interpreted?

See the explanations in the original PR #37093

Note to self:

I don't know if this really solves the issue because I cannot reproduce it exactly but I'm sure that it solves the bug that the image sizes were completely ignored.

To be sure I interpret that correctly, this PR is scheduled to be merged after confirmation of the master fix?

[elpaso]

@m-kuhn no: this is a bug fix I'm 100% sure of it. The only thing I'm not sure about is if this solves completely or partially the bug #33682.

It must be merged.

So "tentative fix", let's close, hope for the best; and reopen in case someone still bumps into it?

Yeah, that's the best we can do, I'm pretty confident this fixes the whole issue but I haven't been to reproduce the "growing" effect described in the bug.

Anyway, the widget was completely ignoring the image size parameters, that is the part of the bug that I'm fixing, whether that was the root cause of the "growing effect" or not, I cannot tell.

Sounds good, looks safe.
