nextTick implementation breaks with core-js@3 Promise polyfill on Tizen 2016

Version

2.6.11

Steps to reproduce

Just cross-linking the issues here, it was opened in core-js repo:
zloirock/core-js#814

The reproduction is not easily doable as it requires a Samsung Tizen 2016 device (which I have because I develop specifically for TVs).

What is expected?

UI updates correctly after events

What is actually happening?

UI will only update if another task is queue.

In the nextTick implementation there's a check for isIOS to trigger an extra setTimeout which, while hacky, works also for Tizen 2016.

Perhaps a PR could be made adding an exception for Samsung Tizen as well?

A boiled down repro is still required

Would you like me to prepare a Tizen package with minimal reproduction code @posva ?

[posva]

The package could be useful for anybody who can reproduce it. A code sample would be useful
It’s unclear why core js plays a role here though. If you have a simple fix, I think it would be better to send a PR

Core-js plays a role in the sense that Vue-cli 4 is using core-js@3 by default for polyfills. The implementation breaks in core-js@3 but doesn't in core-js2, hence my confusion.

@posva a simple fix would be to detect Tizen user agent and do the same trick as it's done for iOS (using a setTimeout), but I noticed an impact in performance while doing user interaction e.g with longpress. I'm curious to know why it worked with core-js@2 with no special quirks.

One solution for me to move forward now is to use core-js v2 on this project, but it seems like going against the grain, as v2 is already deprecated in favor of v3. I don't want to send a PR unless it's absolutely necessary.
