Steps to reproduce

Hello,

Issue found in the insider preview version of Edge (44.18267.1001.0).
It works fine in the currently live Edge version (42).

We found that sending twice a string longer than 4195 characters will
indefinitely break the Runtime.Port instance (and all future instances for that
tab).

We created an extension to replicate the issue, you can find it here (the unexpected behavior is also detailed inline in the comments of the content script).

See also the attach video that exhibits the issue with that test extension.

I am available to help you move forward with this issue (mail, screenshare, phone call, anything), this issue is critical for the company I work for, and our Edge users.

Best regards.
