Looks sensible to me.

Not sure why that check failed. It can't find the CLAP_EXT_WEBVIEW constant - does it know to point at clap:next? I guess this is blocked until (hopefully) CLAP 1.2.7 anyway.

I think it's because the github workflow chose the path where it takes the clap main branch (where CLAP_EXT_WEBVIEW isn't known yet). @baconpaul put some logic in place so that the clap next branch is chosen in some cases. In the log you see that it chose Configure (not next).

The 1.2.7 is why I did this as draft for now 🤷‍♂️

Bumping because 1.2.7 is out, but it's not urgent. I'm not personally using these helpers, but it'd be nice to encourage people who are.

The merged draft extension has a get_resource() method which isn't reflected here.

I'm not sure how to relaunch the tests.

@abique unfortunately this PR was based on an older version of the webview draft extension which is missing the get_resource method (+maybe other changes?)

[abique]

I've done the changes.
