Improve display for long-text custom fields

v.4.0.6

Feature type

Change to existing functionality

Proposed functionality

This is a followup on issue #16830 (opened as bug).

Long text variables make the read-only overview page (e.g. of a device) nearly unusable as it needs a lot of scrolling.

Suggestion: Use a defined height for the text (long) type of custom field and add a scrollbar as it's shown in the edit-view of an object.

Use case

To reproduce:

1. Create a type "Text (long)" custom field for Devices
2. Save a very long text into this field
3. Access the device in the "read-only" view
4. The page gets very long and the user needs to scroll

Hi, I also noticed the same behaviour when viewing a long comment on the Device page. Setting a max-height and overflow on the rendered-markdown class should do the work. I'm also happy to volunteer implement this change !
