There's a comment in there:

// Batch requests which are generally created by us on focus, should not exceed this limit. Check that this is in fact of Incremental type.

As the comment says, batch requests are generally created on input field focus, but not only. The Editor also creates Batch requests when replacing selection with pasted text and the pasted text can be longer than the spell checker limit, as it's happening with this layout test.

Simply remove the assert and the comment since it would be even more confusing without the assert.
