page: Use must-dependency on i-bem-dom__init_auto

[tadatuta]

Otherwise code in page.js won't be called on page load.

[narqo]

it should be a dependency on i-bem-dom in page.deps.js on the level where you introduce page.js file

[tadatuta]

@narqo If so, why there's https://github.com/bem/bem-core/blob/v4/common.blocks/page/page.deps.js#L3 now?

[narqo]

Because our API sucks™.

An i-bem__dom_init_auto dependency has been added after tonnes of complaints from Yandex users, for whom the need for this dependency was not obvious. The dependency was introduced as a standard case solver.

The "must-deps" dependency on i-bem-dom is needed only when page has it's own JavaScript, and it's not what we have in bem-core or any of "average library".

[tadatuta]

I have at least 5 bug reports about it. Why can't we just change it to must? What drawbacks it has?

[tadatuta]

Decided to force users to add mustDeps on i-bem-dom on their own level and not to introduce it in bem-core.
