Strike-through using Markdown does not work in task description

[timholl]

Steps to reproduce

1. Write a task description containing Markdown ~~Foo~~ .
2. Click somewhere outside of the textarea, so it gets rendered by markdown-it.

Expected behaviour

The description should be displayed as "Foo".

Actual behaviour

The description is displayed as "Foo".

Server configuration

Operating system: Ubuntu Server

Web server: Apache

Database: Sqlite

PHP version: 7.2

Nextcloud version: 17.0.0

Tasks version: 0.11.3

Updated from an older Nextcloud or fresh install: Fresh install

Turns out that the global text-decoration:none CSS rule prevents the default style of <s> (as correctly created by markdown-it) inside the #markdown-container.

So a simple additional rule like

23a24,27
> 	s {
> 		text-decoration: line-through;
> 	}
>

in css/src/markdown.scssshould do the trick.
