Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
  • Searched for phrases: line break, line breaking, line end, line ending, line wrap, line wrapping, word wrap, word wrapping, formatting, autowrap
  • The only reasonable issue found is: Word Wrap on "My Filters" tab gorhill/uBlock#2792 (comment)
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

Filterlist's view's formatting's line-breaking at minus sign char -

A specific URL where the issue occurs

moz-extension://092cfadd-d560-4e1a-a80f-ddade5053c9f/asset-viewer.html?url=easylist
moz-extension://092cfadd-d560-4e1a-a80f-ddade5053c9f/dashboard.html#1p-filters.html

Steps to Reproduce

1. Go to 3rd Party filters pane in uBO
2. Click at any filter list so it gets opened in a new tab (eg. EasyList)
3. Scroll down the filter list to any very long filter (eg. multiple domains, eg line 53508 or around in EasyList)

Expected behavior:

Don't break/wrap lines at - (is there any reason to do so?)

Actual behavior:

Notice how ugly/messy the filter looks when line-braked/wrapped at every -, for ex. every domain like happy-foxie.com gets splitted into 2 separate sibling lines:
happy-
foxie.com
