IssueAction dialog resizing even with viewportSize: xlarge

@kchan or @PeterYu do you have any thoughts on this issue? I’m using a xlarge viewport setting and it is getting resized vertically to ~150px and won’t grow even if the content changes to require it. This seems related to the dynamic viewport work done recently that was mentioned
here and here
I found that defining height on the iFrame to 100vh from the chrome developer console as suggested here by @VarunRamnani seemed to show the entire modal. Is there a recommended approach to resolve this?
