Is the music extension restricted to 100 beats per note?

Music blocks don't seem to play notes over 100 blocks long. Is it intended? If it is, why?

To test, go to this project: https://scratch-mit-edu.ezproxyberklee.flo.org/projects/1131687828/ This uses extension blocks, which is music. It uses the rest blocks. Try <100, it'll say correct. But if 100+, it'll say 100.

Intended? Why?

Scratch's source code is on GitHub. I looked at the music extension and yes, it's limited to 100 beats.

https://github.com/scratchfoundation/scratch-vm/blob/develop/src/extensions/scratch3_music/index.js#L704

/**
 * The minimum and maximum beat values, for clamping the duration of play note, play drum and rest.
 * 100 beats at the default tempo of 60bpm is 100 seconds.
 * @type {{min: number, max: number}}
 */
static get BEAT_RANGE () {
    return {min: 0, max: 100};
}

I have a question. Why do they do this?

I assume it's to prevent someone accidentally setting it too high and getting confused why it does something unexpected. The limit at least allows the block to do something. There is also the possible issue of some values not being able to be handled by Scratch (think crashes or similar).

Scratch has a lot of seemingly arbitrary limits.

There is a mention of this limit here:
