Markdown preview for issues and comments is not working.

Recently, I noticed that issue and comment previews are not rendering Markdown properly.  This used to work perfectly, but now it appears that newlines in the input are being ignored.  As such, everything is getting processed as a single line, which breaks many formatting features:

For reference, I am running Microsoft Edge (42.17134.1.0) on Windows 10 Pro 64-bit, 1803 (17134.48).  This occurs with no extensions loaded.

Hi @seraku24,

Thanks for letting us know! We have been able to reproduce this, only for Edge 17. We’ve shared this with our engineering team and they are looking into it. I don’t have a timeline I can share on when this might be fixed, but we are looking into it.


Hi @seraku24!

Our engineering team looked into this, and were able to trace the trouble to an upstream bug in Edge 17.

The Edge team are currently tracking the bug here:

As this issue lies external to GitHub, we’ll need to wait for an update from Microsoft to resolve the trouble.
