[BUG] Viewer shows "Volltext wird geladen ..." when page is loaded with disabled fulltext view

[stweil]

Description

A DFG Viewer test installation with TYPO3 11 and latest code from GitHub for dfgviewer, dlf and slub_digitalcollections shows "Volltext wird geladen ..." although the fulltext view is disabled.

Reproduction

Steps to reproduce the behaviour:

1. Run local DFG Viewer with recent code.
2. Modify URL to show a digitized newspaper issue which has FULLTEXT.
3. Disable the fulltext display if fulltext is shown.
4. Force reload of the page.
5. See "Volltext wird geladen ...".

Expected Behavior

If the page is loaded while the fulltext display was disabled by the user, there should be no fulltext display.

Environment

• TYPO3 version: 11

Another issue: I don't get the search button for a METS with SRU. The official DFG Viewer shows the button for the same METS URL.

Resetting dlf to v5.1.0-rc1 fixes both issues.
