mediapipe: Browser hangs during model loading

While initalizing new Holistic(...) model, browser hangs for 10+ seconds with following output

holistic_solution_wasm_bin.js:9 I0421 21:07:14.783000       1 gl_context_webgl.cc:149] Successfully created a WebGL context with major version 3 and handle 3

Is there any way to load the model without making the browser hang? I used js solution api from https://google.github.io/mediapipe/solutions/holistic.html with zero changes.
