Do we want a comment here why its 13?

Good point. This is copied from the $.fx.interval value & follows the advice from https://github.com/jquery/jquery-migrate/blob/master/warnings.md#jqmigrate-jqueryfxinterval-is-deprecated

Just for my understanding: this check is implemented in jQuery for IE only, bit UI needs it in every browser, right?

Not exactly. jQuery has a check meant for IE but it's run by all browsers so by pure coincidence it makes UI not hit errors here. This is about these lines:

How about:
| // for IE but UI depends on it. | |
| // for IE but is applied in all browsers & UI depends on it. |
?

I still don't understand why we need this in jQueryUI when its already in jQuery... sorry, my mind is a little slow today ;)

jQuery 3.0.0 & newer require DOM elements with the getBoundingClientRect method. It's just that jQuery needs to run a check for getClientRects() due to the comment above the lines I linked, to workaround an IE issue. We shouldn't rely on this check for other purposes.
Also, jQuery Migrate warns if you use offset() in such a way.
That said, now I see the discussion in jquery/jquery#2310 so maybe I need to re-read it & make sure Migrate is not warning too much.

Ahhh, got it. Thanks for the explanation and your patience :-)

@fnagel Thank you for raising these concerns! This change will most likely not be needed as we'll update Migrate instead.

This also adds a new internalthis part is now extracted to #1922.$.ui.__safeOffset__method to provide a similar support to past jQuery versions while avoiding Migrate warnings.
