Back navigation breaks communication in Safari

[Benjadahl]

Hi,

We are using webext-bridge to create a cross platform extension deployed to Chrome and Safari on Mac and iOS.
We found an issue that occurs when using the back button, but only on Safari.
When navigating back, sometimes following sendMessage requests will never resolve. (Using the native chrome.runtime API does resolve correctly). We tried to use the [email protected] release instead - it seemed to improve the succes rate from 0% to about 50%, however it still has issues.

Would you like for us to provide a repository reproducing the issue? And is there any way else that we can contribute to fixing the issue?

Thanks a lot

What browsers have you confirmed [email protected] to be working correctly?

According to our tests:

• It works in Chrome
• It fails in Safari (on MacOS)

Safari is something I don't have expertise in, so unfortunately I won't be able to help code wise. Please see if you can find a solution, a PR would be very welcome.

Alright, we'll take a look tomorrow. Do you have any idea where in the code, it might be relevant for us to search?
