Endless loading for all files except .txt and .md

[Pilzinsel64]

Steps to reproduce

1. Open the files app in a browser
2. Navigate to a directory that is your own.
3. In the files app just create a new file called "test.json".
4. If the text editor does not open automatically, click on the files.

Expected behaviour

Until v18.0.0 It was possible to click a file (or while creating a new one) and then the text editor showed up. After one or two seconds I was able to see and edit the content.

Actual behaviour

When I click on a file, like .php, .json, .xml, the text editor does open but keep loading without showing the content.

In Settings->Protocoll there is no error or any log.

I have three nextcloud instances on very different servers. On every instance I get the same problem. With different Windows clients and different browsers. This bug does not happen in the Android-App btw, only in the browser.

This issues seems to be same as #651 but I want open a seperate one to post everything you need seperatly.

Hi,

when this app is enabled, i have an infinite loading icon on the front of file app (default page after logon).
No particular error in logs.
This issue happen, since upgrade from 17.0.4 to 18.0.4.
I have to disable file app to remove this loading icon on file app.

thx.
