Pagescroll bug fix

[pavel1992]

When using angular sticky directive in project, found the bug with page scrolling at new element on page adding. It was because throttledResize function triggered even if window not actually resized. This pull request fixes that bug with comparing width before and after resize event.

Hello,

Thanks for the pr. I notice it doesn't pass the unit tests, can you take a look at that? I've posted some code-review comments in your changes

Hello, it seems test fails because it throws resize event with no width actually changing, so after my fix it doesnt triggers resize function. I don't know at this moment is this expected behaviour or not, but IMHO you shouldnt trigger resize when it was no really resizing.

'window.dispatchEvent(new Event('resize'));' <- thats why test fails.

I don't remember exactly, but I'm pretty sure it's their for a reason. I think it will automatically be resolved if you fix the review comment I gave because than there's something to flush.
