No open button after installing .deb package

[Yousuf 'Jay' Philips]

Steps:
1. Double click on a .deb package
2. Software opens up
3. Click 'Install' button
4. After installation, there is no 'Open' button that is normally there when installing other software

Tested on Xubuntu 19.10 daily

Thank you for your bug report. Could you add your 'journalctl -b 0' log after getting the issue?

I can observe the problem in a stock Ubuntu 19.10 VM, after installing the google-chrome-stable deb from chrome.com.
Attaching journalctl, the following lines look like they might be related to the problem:

Marking as rls notfixing. This doesn't mean that we won't fix this bug, but that we won't block the release of E on getting it fixed.

FTR this doesn't appear to be a regression, there is no "open" button after installing the chrome deb on 18.04 either.
