download list of Software Updater (update-manager) does not adjust height while sizing window

in ubuntu 18.04 LTS (Bionic Beaver) release there is still an issue with the update-manager (Software Updater).
when there are updates available to download and install, then while downloading you can expand the donloading details of current downloading items list. when you then enlarge the window at the height, the list is not follow in its height.
(see screenshot)
"the issue ... download list didn't adjust the height (Step 5)"

i think to recall that this issue was already reported for ubuntu 17.10 as "follow up" of a similar issue of update-manager (https://answers.launchpad.net/ubuntu/+question/663622 -> https://bugs.launchpad.net/ubuntu/+source/aptdaemon/+bug/1690541).
the main part is fixed but the part i report is still an issue.
i was instructed to do a new report, so here it is...

Description: Ubuntu 18.04 LTS
Release: 18.04

to reproduce in ubuntu 18.04 LTS:
1. open "Software Updater"
"the icon of "Software Updater" (step 1)"
2. when there are updates available click the button to install available updates.
3. in case there are multiple items to download and their size i big enough, that the download progress takes time, you will see a download message where you can see Downloading <package-name>.
under that string there is a Details region that you can expand. click on that Details to expand ans see the list of downloading items.
4. with your mouse go to thew bottom of the window of "Software Updater" and grab the lower border further down to enlarge the windows in its height.
5. you will see, that only the windows will grow, but the lit of downloading items stays as small as in its initial height.

i would expect that the height of the list will grow in the same amount as the windows height does.
