TYPO3 Core

Test case:

• Assign a normal filemount, e.g. for 1:/test (Folder test in storage 1) to a user
• Set a read-only filemount for the root path of storage 1: options.folderTree.altElementBrowserMountPoints = 1:/

This is the case in an environment where editors only can manipulate certain folders (e.g. of their departments), but should be able to read/use all file of the website.

Now, after switching to a non-admin user that has both filemounts assigned, a click to "test" in the File List module leads to an "endless" call that is terminated at max_execution_time.

This problem was introduced with https://review.typo3.org/#/c/39898 in #67245. Before (or without) that change, this setup works/worked fine.
