Current behavior:

Hi guys, I'm seeing a bug only on iOS where I am able to scroll the content of a page in the background of a modal when this latter is opened and when I try scrolling inside the modal. Is there a way to prevent this ?
Once again thanks for your effort to try making Ionic a great framework
Expected behavior:

Content of a page in the background of a modal should not scroll when scrolling inside an open modal
just as it does for Android

Hello, thanks for opening an issue with us! Unfortunately, on UIWebView there is no good way to stop scroll events from reaching a page underneath an overlay without causing jank and rendering flashes. However, on WKWebView it is possible to stop scrolling underneath an overlay in a performant way. To get WKWebView you can check out the instructions on this repo. We are planning on making this the default webview for iOS soon.

Hi I did have the WKWebView plugin before posting and the issue is still there. Tested on ios 10.3. Please reopen the issue

Hey. I'm running into the same issue. Has there been any progress on this?

@jgw96 this is still an issue even in WKWebView.

There’s a number of duplicates of this issue logged and unfortunately none of them seem to get any attention from the ionic team.
