'-webkit-text-size-adjust' is not supported

Hi guys!
I used developer tools for inspect HTML-pages generated by Phoenix and got this error:

ERROR: ‘-webkit-text-size-adjust’ is not supported by Chrome, Chrome Android, Edge 79+, Firefox, Safari. Add ‘text-size-adjust’ to support Chrome 54+, Chrome Android 54+, Edge 79+.

I find this line in priv/static/assets/app.css:

html {
line-height: 1.5;
/* 1 /
-webkit-text-size-adjust: 100%;
/ 2 /
-moz-tab-size: 4;
/ 3 /
-o-tab-size: 4;
tab-size: 4;
/ 3 /
font-family: ui-sans-serif, system-ui, -apple-system, BlinkMacSystemFont, “Segoe UI”, Roboto, “Helvetica Neue”, Arial, “Noto Sans”, sans-serif, “Apple Color Emoji”, “Segoe UI Emoji”, “Segoe UI Symbol”, “Noto Color Emoji”;
/ 4 /
font-feature-settings: normal;
/ 5 */
}

How to fix this error? Simply comment out this line or replace it with something else?
