Title: Fix one click postage keyboard shortcuts for tumblr change

Ignore any posts which are not currently visible when determining which post is at the top of the screen.

Once the 3rd or 4th post is on screen tumblr appears to now hide the posts at the top of the screen, which causes the keyboard reblogging to reblog the first post instead of the post currently on screen. This fix ensures we ignore anything that's currently invisible.
