fix: firebase crashlytics reports part 1 (#1113)

* fix: trim surrounding whitespace in url link in articles

* fix: invalid url throwing exception

* fix: missing argument type

* fix: missing description in episode view

Some episode descriptions are not HTML content

* fix: cannot scroll on youtube embed

NOTE: fullscreen seems to have broken in the package side
