I noticed a bug with liking the currently playing song in the desktop app on Windows 10 (app version 1.1.21.1654.g282a2807).

Steps to Reproduce:
* Begin playing a song that is not in your liked songs (not sure if it matters from where, but I did this from a playlist)
* Click the heart icon next to the song name in the bottom left of the screen (the now playing area)

Expected Results:
* The song is added to your liked songs

Actual Results:
* The song is not added to your liked songs
* There is no visual interaction (no tooltip on hover, no click effect)
* The heart icon looks disabled (slightly lighter gray color)

Notes:
* There is a workaround to this by first liking the currently playing song using the like button within the playlist area
* This bug does not occur for songs that were already liked before you started playing them
