summary window expands, cutting off buttons with 800x600 screen

[ԜаӀtеr Ⅼарсһуnѕkі]

STEPS TO REPRODUCE
 0. Ensure you're using an 800x600 resolution
 1. Load the Lubuntu 19.04 installation media
 2. Click to icon to Install
 3. Complete all the steps up to and including the step to put in your username and password
 4. Click Next

EXPECTED RESULTS
Summary window stays the same size as previous.

ACTUAL RESULTS
Summary window enlarges. Furthermore, if you go back to the previous screen, the enlarged size remains. Additionally, it appears the enlarging occurs both up and down because the top of the screen is filled and the buttons are cut off.

WORKAROUND
Maximize the window.

NOTES
We will likely move to full screen by default in 19.10 and beyond:
