setDefaultOptions overrides options when called again.

[a-eid]

🐛 Bug Report

this might not be the case for every options but it is when you set layout it does override at least animations.

To Reproduce

• call setDefaultOptions and set some animations push or setRoot.
• call it again for whatever reason you want, calling it empty also work, but in my case I was calling it to change the direction of the app layout.direction rtl | ltr.

Expected behavior

just calling setDefaultOptions overrides the animations key set before.

Actual Behavior

setDefaultOptions show merge and not override.

Your Environment

• React Native Navigation version: ^9.8.0 & ^7.9.0 & ^7.10.0
• React Native version: 0.63.4
• Platform(s) (iOS, Android, or both?): both
• Device info (Simulator/Device? OS version? Debug/Release?): debug ( I assume it behaves the same on release ).

hey @a-eid, shouldn't you be using MergeOptions when you want to change it after setting the DefaultOptions?

It makes sense to me that it'd wipe the other options you've set if you set DefaultOptions a second time.

[a-eid]

@AlphaJuliettOmega in some cases you have to use setDefaultOptions, if I remember correctly you have to use it when setting the direction of the layout or something, if you want I can check and report back.

also actually it specifies in the does that setDefaultOptions merges with the previous one.

setDefaultOptions() through merge is very useful for unmount components. Hope can fix it!
