norton287 commented 2 years ago

Description

Unable to scroll content in the Webview control on Android SDK 31, works fine on iOS and UWP though

Steps to Reproduce

  1. Create a webview control with any source
  2. load enough content that should force the view to be scrollable
  3. when it should become scrollable on SDK 31 it is just locked solid

Expected Behavior

Content should become scrollable when it fills past the view

Actual Behavior

Contant stays static and unscrollable, can load new content but cannot scroll back up to see previous webview content.

Workaround

Haven't found one yet, will be trying earlier SDKs to see if the issue is there as well later today and tomorrow.

Thanks for the report @norton287 did you get around to testing other SDKs?

norton287 commented 2 years ago

I tested SDK 29 & 30 and it occurs there as well

Would you be able to provide a reproduction sample of this? Because I don't seem to be able to get this behavior in my test

norton287 commented 2 years ago

Give me an email and I can send my solution to you. I think it may be the url I is wrapped in an iframe.

@jfversluis a little more background...

The url is for an azure chat bot, to get around rendering issues on iPhone they wrapped the end point in an iframe.

norton287 commented 2 years ago

@jfversluis haven't thought about it but after I get out of class this morning I will remove the URL from the iframe for Android and see what happens.

jfversluis commented 2 years ago

Unfortunately I can't look at any private code, if you want to share something it has to preferably be on a public (GitHub) repo :) Let me know what you find!

norton287 commented 2 years ago

Stripping out the URL from the frame of the web chat bot does not work. It does the same thing.

In order for you to test your are going to have to setup a web chat bot and test with the endpoint url they give you.

Or you can use mine if you want, just cannot release it public as the potential for abuse.

@jfversluis I can share the URL endpoint with you for your source in a demo you create but I cannot publish it as it is an item that can rack up a lot of money in a short time if misused and spread around. Otherwise, you need to go to the portal and set up a simple chatbot and try it out.

norton287 commented 2 years ago

@jfversluis Added you as a collaborator to the repo, you can extract the URL from the About.xaml.cs file under Views in the repo to test with.

@norton287 as mentioned, unfortunately I can't look at private/proprietary code without all kinds of thing that need to be arranged for that. Sorry. Additionally, I don't want to ship it off as "not our problem" but it seems that our WebView is working fine and the problem lies in how the page is constructed. How does it behave if you go to that URL in the regular web browser on that device? I expect it to show the exact same behavior.

norton287 commented 2 years ago

@jfversluis The issue is that it will not scroll if the page that the webview is located on is wrapped in a ScrollView. Removing the scrollview allows the webview to scroll. The tag only affects Android. So there's the problem.
