Hi experts,
I embedded my canvas powerapps to my SharePoint modern page using powerapps webpart and Iframe. My issue is if I scroll down to the bottom of my sharepoint page, a black color also appears in my powerapps iframe bottom part. if I scroll up my page the black also start disappearing while scrolling. this issue is when using chrome browser.

My powerapps do not have a scroll and the iframe is exact fit with the app.
Thanks in advance for helping.
