"Hide from Reddit" doesn't hide on reddit page.

[ROFISH]

Tap on a story. Then tap on the comments while on the story. Then tap "Hide on Reddit" from the menu. Go back to the story, and go back to the reddit, it is not hidden.

If you select "Hide on Reddit" from the story, or if you go directly to the comments, it will hide it on your list, but only if it's a first layer. However, if you select hide from a second layer (ie. comments from story or viewing story from comments), it won't hide on the list of links.
