5.0.0 breaks back button in preact-router

[merlinstardust]

When attempting to upgrade to [email protected] in my preact app, the back button no longer works as it did previously. [email protected] works fine.

I found this issue in preact-router but I think this may be a fix that history needs to do.

It may or may not be related to this comment on the v5 undocumented breaking changes thread.

This comment makes me pretty sure that the breakage came from the change in signature for the history.listen() callback.

I documented that in my gist here and midahp effectively came up with the same workaround.

It sounds like this is an issue that preact-router needs to fix to be compatible with v5.
