Go: Apply Cover Profile can't find file

[TannerShmoog]

Using the Go: Apply Cover Profile command provided by the extension, profiding an absolute path /home/tanner/.../profile.cov works fine, but giving it just the file name does not, even if it is in the root directory which vscode is open to. In the source it looks like this is because the applyCoverProfile function fails before ever checking a working directory while the call to applyCodeCoverageToAllEditors confusingly does set the working directory. Is there something wrong with my config that is causing it to be unable to find the working directory? This old issue seems related #610 but it seems to have been addressed...

export const applyCoverprofile: CommandFactory = () => {
	return () => {
		if (!vscode.window.activeTextEditor || !vscode.window.activeTextEditor.document.fileName.endsWith('.go')) {
			vscode.window.showErrorMessage('Cannot apply coverage profile when no Go file is open.');
			return;
		}
		const lastCoverProfilePathKey = 'lastCoverProfilePathKey';
		const lastCoverProfilePath = getFromWorkspaceState(lastCoverProfilePathKey, '');
		vscode.window
			.showInputBox({
				prompt: 'Enter the path to the coverage profile for current package',
				value: lastCoverProfilePath
			})
			.then((coverProfilePath) => {
				if (!coverProfilePath) {
					return;
				}
				if (!fileExists(coverProfilePath)) {
					vscode.window.showErrorMessage(`Cannot find the file ${coverProfilePath}`);
					return;
				}
				if (coverProfilePath !== lastCoverProfilePath) {
					updateWorkspaceState(lastCoverProfilePathKey, coverProfilePath);
				}
				applyCodeCoverageToAllEditors(
					coverProfilePath,
					getWorkspaceFolderPath(vscode.window.activeTextEditor?.document.uri)
				);
			});
	};
};
