problems with .sh files

[szaimen]

Describe the bug
I cannot edit or show .sh files when I am logged in.

To Reproduce
Steps to reproduce the behavior:

1. logg into the Nextcloud
2. create a test.sh file and click on it to open/edit the file
3. the text app opens but just loads forever

Expected behavior
It should open the file so that I can read/edit it.

Good to know
Strangely enough I can view/edit that file when I share it directly over a public link. Then it gets shown correctly and loads the content.

Client details:

• OS: tested on windows 10 and Android 10
• Browser: tested on a chromium 80 based browser and firefox 73 on

Text app version: (see Nextcloud apps page)
1.0.2
Operating system:
ubuntu 18.04 LTS
Web server:
apache2
Database:
postgresql
PHP version:
7.2
Nextcloud version: (see Nextcloud admin page)
18.0.1

Additional information:
I found this error while opening the file in the browser console:

I have the same problem on a file with the php extension, loads forever.
If I duplicate the file and rename it to .txt > it works, renaming to .html > also works
Pretty weird.

EDIT > Also, if I try to open the php file and then cancel (when it is forever loading) it will break the app and I will need to refresh the page for it to work again. Meaning that it won't open any files (not even .txt until the page is hard-reloaded).

EDIT2 > this seems to be a duplicate of #651

EDIT3> I tried to change the 'mimetypesmapping.json' to make all code seem like 'text/plain', but that also didn't fix the problem. Text seems to ignore that config. Seems there is some problem to load any code files.
