Galaxy: HTML data displays as a blank page at http://usegalaxy.org

Issue

Click on the "eye" icon to review an html output dataset (FastQC html report, MACS2 callpeak html report) and the result is a new blank middle panel, no content.

Reported at Galaxy Biostars, confirmed on Main

@martenson Let me know if you have any particular ideas I can track down. First hunch was something new with the main configuration, but now I'm looking at the recent sanitize_html changes.

[dannon]

@jennaj Can you give me a list of affected tools which output html reports like this? I've fixed it for fastqc. (underlying issue to dig at still, but it's resolved for main's purposes, that is)

[martenson]

@dannon Barcode Splitter is another one I heard about

[dannon]

2263 should resolve this in a more permanent fashion, restoring functionality to how it was before.

The whitelist exceptions I added for these tools, though, might should probably stay. The reports look _way_ nicer for fastqc for example. We just need to make sure they're super safe.

[martenson]

The outside links in the unsanitized fastqc will yield errors as they usually go to non https urls (e.g. on Main). :/

[dannon]

@martenson Cool. We can work on the pretty whitelisted display in a different issue, but #2266 should fix the root issue here and we can remove the whitelisting for tools that it's not wanted (or where it exhibits this problem) and work on that next.

[dannon]

@jennaj Should be resolved now, #2266 has been applied to main.
