Newer versions of Android WebView and Android Chrome are no longer compatible with the spellcheck attribute #21255

Closed Lukenickerson closed 1 year ago

Lukenickerson commented 1 year ago

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

The browser compatibility listing for the spellcheck HTML attribute (https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/spellcheck#browser_compatibility) lists WebView 47 and Android Chrome v47 as working. What I've found in my own testing is that WebView v91 does allow spellchecking, whereas WebView v119 does not. Also in Android Chrome v119 you'll see there are no settings for spellcheck.

I suspect that spellcheck was disabled at some point in WebView (and thus also Chrome Android). You'll see that last year in 2022 there were a number of articles about "spell-jacking", warning that Chrome and other browsers could leak passwords.

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet)

What did you expect to see?

Ideally for Android WebView and Android Chrome there would be a version range listed as compatible with the spellcheck attribute, and then a version range where it is no longer compatible.

At very least there should be some kind of warning that this data is potentially incorrect.

Did you test this? If so, how?

I added the spellcheck attribute to a field with misspellings, and ran it in a Cordova Android app -- both in an emulator with an older version of WebView (v91), and deployed to an actual Android tablet with a newer version of WebView (v119). In the old version of WebView, the red squiggle lines showed up under the misspellings, whereas with the new WebView, nothing happened.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

I could not find any release information about this from Google or the WebView team. Sadly WebView doesn't appear to be in GitHub, with Issues and discussions easily accessible.

Do you have anything more you want to share?

Sorry, the title was just the default, but I've fixed it. Is this all good bot?
