Hi @naydav,
I've updated PR's code.
Pls, check.

[lenaorobei]

Please replace the core usage Magento\Newsletter\Observer\PredispatchNewsletterObserver with your implementation and remove unnecessary dependency.

[lenaorobei]

This is a redundant dependency.

@sedonik, how is your progress with this ticket, are you interested to finish it?

[lenaorobei]

Please remove redundant fixtures and use @magentoConfigFixture instead.

[lenaorobei]

Once it is fixed, please squash all commits into one. Thanks.

Hi @lenaorobei,
I've set @magentoConfigFixture but after that WebAPI Tests build failed. Could you advice, please?

[lenaorobei]

@sedonik need to check ScopeInterface::SCOPE_STORE in the isActive method.
