Bug: Removing animation-timeline:view();

This plugin is removing animation-timeline:view();

@supports (animation-timeline:view()) and (animation-range:entry -20% cover 25%){@keyframes appear{from{opacity:0;scale:0.8}to{opacity:1;scale:1}}.entry-content img{animation:linear appear;animation-timeline:view();animation-range:entry -20% cover 25%}}

After

@supports (animation-timeline:view()) and (animation-range:entry -20% cover 25%){@keyframes appear{from{opacity:0;scale:0.8}to{opacity:1;scale:1}}.entry-content img{animation:linear appear;animation-range:entry -20% cover 25%}}

Currently I am adding the CSS in header.php instead style.css to override the bug, hope to fix in future update. Also, tried to ignore .entry-content img in ignore CSS setting, but not seems to work.
