Status messages obscure navigation

[astrosticks]

Clicking to progress through questions quickly, as one might if they don't remember what lesson/section they're on, is extremely slow, because activity pages immediately displays a compiler status message over the "next" link.

Steps to reproduce:

1. Go to https://cs-education.github.io/sys/#chapter/0/section/0/activity/1
2. Try to click the "next" link immediately after the page loads- you can't! Unless your system is running slowly.
