 This is one of the remaining issues of #21766: our external helper app
 dialog blocker leads to a stalled download using the download button on
 the pdf viewer. Right-clicking and using Save as... is still working,
 though.

 mcs wrote in #21766:
 {{{
 We have not found a fix for the pdfjs download problem, but I think the
 reason our earlier fix is ineffective is because a blobURI is used for the
 download, and therefore the channel associated with the download cannot be
 suspended (suspend and resume are only implemented for some channel
 types). So in this case the suspend/resume solution won't work.
