Content is still scrollable when alert/actionsheet is visible (RC4, iOS)

When alert or actionsheet are being shown, I can still scroll the content in the background through the backdrop.
This happens only on iOS and I couldn’t find any posts talking about this.

Does anyone have the same issue?

Oh I just found the reported issues on github.

Yes, I have. Able to scroll the content when alert is visible.
Did you find any solution?
