'JS RegExp Negative Lookbehing iOS Chrome

I have written web app where Im using RegExp like this -> new RegExp("(?<!<[^>]*)", "gi");. The JavaScript is working fine on UNIX/Windows/MacOS using Chrome browser (doesnt work on Safari...).

But on iOS (don't know about Android) when I Launch Chrome the regex is not working.

Is here any way how to debug ios Chrome webapp?

Thanks for all the replies

EDIT #1: Android chrome works just fine.
