 When I load this URL, the first time I get meaningful output:
 > [[Image(1.png)]]
 But if I hit Ctrl+R to refresh, I get this garbled (maybe compressed?)
 output instead:
 > [[Image(2.png)]]
 If I refresh again, it goes back to the readable version, and if I refresh
 yet again, it switches back to the garbled version. I can keep switching
 back and forth.

 The same happens if I click the refresh icon in the address bar. I tried
 it in Tor Browser 6.0a4 and Chromium 49.0, and it happens in both.

 The garbled version additionally causes this to be printed to the console:
   The character encoding of the plain text document was not declared. The
 document will render with garbled text in some browser configurations if
 the document contains characters from outside the US-ASCII range. The
 character encoding of the file needs to be declared in the transfer
 protocol or file needs to use a byte order mark as an encoding signature.

 With another type of document, namely
 https://onionoo.torproject.org/details?lookup=88F745840F47CE0C6A4FE61D827950B06F9E4534,
 the text remains readable while repeatedly refreshing, but the "character
 encoding" message appears in the console in alternating refreshes.
