I have recently run into an issue where my gallery does not render correctly in Preview mode (F5). This issue only appears when the number of rows exceeds the height of the Gallery (i.e. when I have a scorllbar). When the gallery is sized so all rows can appear in the gallery, the issue does not occur. As a side note, I have also noticed this when I have a form that has a scrollbar and I have noticed that the scrollbar has become super thin.
I have a canvas app with an Azure SQL backend. I am using Chrome Version 78.0.3904.108 (Official Build) (64-bit). I have tried logging out, clearing the cache and internet history and logging back in. This does not appear to correct the issue.
The issue does not appear during design, only in Preview mode. The issue does not appear in the published version.
I have attached samples for you to review. There is one attachment for the Design view and one for the Preview view.
Any help would be appreciated. If you need any other information, please let me know and I will try my best to get it for you.
