manifests.webapp.share_target - Chromium doesn't support it on Linux

What type of issue is this?

Missing compatibility data

What information was incorrect, unhelpful, or incomplete?

Chromium (and Chrome as well) doesn't supports share_target on Linux. At least KDE has sharing mechanisms, but it's not supported by Chromium PWAs

Maybe this table was made before the official release of Chrome on Linux, and it's the reason why the table doesn't count it as an only partial support

What browsers does this problem apply to, if applicable?

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

What did you expect to see?

Yellow support indicator next to chromium based browsers, and a remark about absence of Linux support

Did you test this? If so, how?

I tested in my app, and in photopea (it has share_target in the manifest) - it doesn't appear in Dolphin file manager share menu (even after system reboot). File handling works fine though

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

Here people mention absence of linux support

MDN metadata

Start with the BCD entry queried as manifests.webapp.share_target and compare its Chromium-based browser data with the linked Chromium issue and MDN page. Update the compatibility data to reflect missing Linux support, including the expected partial-support indicator and remark, then validate the data changes.
