importExportRateLimiting setting ignored, CORS header ‘Access-Control-Allow-Origin’ missing

Hello,

There seems to be a bug when trying to export several Markdown files (two or more) in a short amount of time. I don't have this problem with the other types of exports. Here is the message I get:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://pad.mywebsite.com/p/demo_2/export/markdown. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 200.

My guess is that Express needs to be configured the same way it's been configured with Etherpad to handle this kind of requests? Maybe the solution lies somewhere there, but I'm by no mean an expert.

My Etherpad version is 1.9.3, so maybe it just hasn't been covered yet.
