That's because most material design implementations are half baked. There's very specific timing requirements to get most of the UX e.g. the inkwell to feel realistic and often the web variants are not styled well (they have random latencies partially due to the DOM/JS bindings). Material design is a pain the ass to implement faithfully as they are extremely latency sensitive. Try the Flutter and native Android/Kotlin Jetpack compose if you want a feel what they are suppose to feel like.
