testing.toggleInlineCoverage action is available when it shouldn't be

Does this issue occur when all extensions are disabled?: No - related to VS Code API for extensions that create Test Runs

We programmatically use the VS Code API to createTestRun and we create Test Runs without a TestRunProfile. As per the docs:

extensions may programmatically create requests not associated with any profile

Our extension also sets file coverage for the test run with the addCoverage method.

In the editor/title, we see the testing.toggleInlineCoverage action appear when it does nothing. The VS Code API to provide the coverage for this action is surfaced via the TestRunProfile, which is undefined in our case.

Unless I'm missing something, it seems that the action should be hidden in our case, and this is a bug?

Does your extension provide per-line coverage information? The action will always appear when coverage is reported, but if you do not report per-line/statement coverage information, then none will end up being shown.

We are reporting the overall file statistics with:

testRun.addCoverage(
              new vscode.FileCoverage(
                vscode.Uri.file(this._absoluteFilePath(coverage.file)),
                new vscode.TestCoverageCount(coverage.covered, coverage.total),
              ),
            )

but we're not reporting per-line information. So in our case, the toggle action is appearing, but it does nothing because we don't have a TestRunProfile to do anything; nor do we currently surface anything beyond summary level data for the file within VS Code.
