.children() does not return text nodes when using mount

[hahnbi]

Current behavior

When calling .children() while using mount(), text nodes are not present in the result.

Expected behavior

When calling .children() while using mount(), text nodes are present in the result (similar to when using shallow()).

After doing some code exploration, I see that .children() on ShallowWrapper doesn't automatically filter out any nodes:
https://github.com/airbnb/enzyme/blob/9e26937c12a46c9915327d913b2a9fd3e711476e/packages/enzyme/src/ShallowWrapper.js#L1222-L1224

...while on ReactWrapper, it filters out non-object nodes:
https://github.com/airbnb/enzyme/blob/9e26937c12a46c9915327d913b2a9fd3e711476e/packages/enzyme/src/ReactWrapper.js#L767-L769

Does anyone know what the intention is behind filtering out these children nodes?
