To be fair, the native browser controls have had too many quirks and features fox UX/UI consistency.

Corporate needs their Brand™ look precisely as specified in their expensive Style Guide. IBM wouldn't want the Google vibes of Android Material Design TextFields, I imagine.

Scratch beneath the visuals, and starker technical differences appear.

Safari on iOS (used to?) has a 350ms debounce delay on every tap / click, in case you want to do a multitouch gesture.

JavaScript (Frameworks) were the only way this arbitrary delay to user input could be reduced before 2015, when Apple finally released a native API for this.

Well, too many to have a single website be consistent across browsers.

But as a user I'm using one specific browsers, and I expect all websites be consistent for that browser.
