Impossible to change status of an imported remark as 'won't fix'

A SonarCloud user with the ‘Administer issues’ permission is unable to change status of an imported remark as ‘won’t fix’ or ‘false positive’ (while it’s possible to do for native SonarCloud remarks).
See an example for a StyleLint-imported remark:

Hey there.

This is intentional. For imported issues, you should use the suppression mechanism native to that tool. See the docs for Stylelint
