Comment:

 Problem is "return null" from external-app-blocker.js
 Removing it solves everything except spamming of error console with
 warning, that is why hack with returning null was needed in first place.

 Proposed new hack solves noise in console by returning string "text/plain"
 that code can accept. Code will use "text/plain" anyway for case like this
 ticket describes. Hopes nothing another will be broken with new hack. Need
 to test.

 Patch attached to ticket.
