Hello MathiasBynens,

Based on recent testing, the issue is not reproducible which will be closed out to reflect this. Should you happen to see the problem as still active in Win 10 / MS Edge please feel free to activate the feedback and reply.
Please note that we are not working on IE feature bugs any longer at this time unless they are security related.

All the best,
The MS Edge Team
