Description

Switching files in the preview no longer cuts the URL at a # in the folder name (Doc#A/b.png became Doc), so reloading and deleting in such folders work again. The personal/home redirect also keeps the folder now.

Related Issue

• Fixes Image preview and drive redirect lose the folder when its name contains # #4160

How Has This Been Tested?

• test environment: unit tests (Vitest), browser tests (Playwright) against a local OpenCloud
• test case 1: unit: preview file switch and drive redirect keep an encoded # in the URL (real router)
• test case 2: browser: next, arrow key, photo roll, reload, close and Back in a # folder (desktop and Pixel 7), deleting in the preview, personal/home redirect; plain, unicode/% and public link folders unchanged
