Downloads view in update manager can't resize properly

[ZdravkoG]

When there are new updates and update-manager goes to download corresponding packages, download list can't follow main window resize (more precise in vertical direction). This is inconvenient (and ugly) when there are many packages and I want to see as much as possible (especially when there are packages from different repositories).
I made a little investigation and have found that the issue comes from AptDetailsExpander class in /usr/lib/python3/dist-packages/aptdaemon/gtk3widgets.py. There are 2 possible views: AptDownloadsView in ScrolledWindow and AptTerminal. AptTerminal seems to work fine, but the other view - no. More deep look shows that AptTerminal initialization calls set_vexpand(True), ScrolledWindow don't have such call! Adding such call for ScrolledWindow initialization fixes the issue for me.
It's good idea this to be fixed in ubuntu repositories. Example patch is also here (at least as starting point).

Is there any reason why this bug is ignored from Canonical side? If there are need some additional info, could somebody tell something. For Ubuntu 18.4 (Bionic) there is new aptdaemon revision (LP: #1831981 -> 1.1.1+bzr982-0ubuntu19.1), but the file /usr/lib/python3/dist-packages/aptdaemon/gtk3widgets.py in the package python3-aptdaemon.gtk3widgets is not even touched. Why?
Updated package just replace the fix (of course).

Hi @ravikantcool, can you point me out what exactly is incomplete???!

Whenever gtk3widgets gets updated, I have to patch it again and again, every time, so be possible works (correctly visualizes, more precisely). That's it! What's not clear?! Just a simple line seems missing in the code. Take a look on the patch provided. Without the line, packages list size almost freezes.
It's the same on both 18.04 and 20.04. I'm getting curious, am I the only experience this? 🧐 On fresh installed 20.04 keeps the same!

If something else is needed, point out, please. 🤔
