|
* and this callback will be called.

* Our fix is to check if the index is the same as the previous index

|
* and if the incoming path is the same as the old path but with the hash added,
|
|
* then treat it as a push instead of a reset
|

|

* This also works for subsequent hash changes, as internally RN

|
* doesn't store the hash in the history state.
