Addition to the accepted answer;
Providing the specified property only to the host element or body element, while holding some objects (images and SVG elements, etc.), still causes a tooltip.
* { -webkit-user-select: none; -webkit-tap-highlight-color: rgba(0,0,0,0); }
Providing properties to all elements (*) helped.
I also assume that the select user has a problem / error with text input, so you can exclude it.
input { -webkit-user-select: auto; }
