Shared Storage API & Fenced Frames API & Protected Audiences API may not supported in webview
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?
viewing https://source.chromium.org/chromium/chromium/src/+/main:android_webview/tools/system_webview_shell/test/data/webexposed/not-webview-exposed.txt, I notice the three APIs (also a ServiceWorkerRegistration.periodicSync property, the Periodic Sync API itself is disabled in webview) is in the file, but mark as supported in webview
- Shared Storage API
- https://chromestatus.com/feature/6256348582903808 also says not supported in webview
- Fenced Frames API
- https://chromestatus.com/feature/5699388062040064 also says not supported in webview
- Protected Audiences API
- The same, but it's data is very raw.
What browsers does this problem apply to, if applicable?
Chromium (Chrome, Edge 79+, Opera, Samsung Internet)
What did you expect to see?
mark those features as not-supported
Did you test this? If so, how?
no, simply check using chromium source code
Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

viewing https://source.chromium.org/chromium/chromium/src/+/main:android_webview/tools/system_webview_shell/test/data/webexposed/not-webview-exposed.txt, I notice some feature should not be marked as supported in webview, but it is incorrectly marked as yes
HMM, looks quite machine-friendly: I wonder if it would be practical to extract the information mechanically from the git history?
The file from Chrome's you mentioned had been taken into consideration years ago when most updates to BCD were still performed manually. Now, almost all data is collected by https://mdn-bcd-collector.gooborg.com automatically.
If BCD reports that something in WebView is supported but it's in that file, it's either because:
- It's actually supported after all, so that source file is wrong
- It's incorrectly exposed and overrides need to be added to the collector
Do you have access to WebView on Android? If so, could you test which features are actually unsupported?

Yes, as I later made some check, most old APIs seems to be correct, but some newly added API (like Shared Storage API, Fenced Frames API, which seems to be added mantually) seems to be wrong.
(Previously I only checked some items at the end of the file content)
I've updated the title and description and has confirmed the three APIs has different data with current one.
