width parameter is ignored for embedded YouTube video iFrames

[Alega-ua]

I attached the MD file Torus.md, it's code:

<iframe src="https://www.youtube.com/embed/u0eOuxJX36g" allow="fullscreen" allowfullscreen="" width="300" style="aspect-ratio: 16 / 9; "></iframe>

<iframe title="Blender Abstract Torus" 
src="https://www.youtube.com/embed/u0eOuxJX36g?autoplay=1&showinfo=0&playlist=u0eOuxJX36g&loop=1" height="200" width="300" allowfullscreen="" allow="fullscreen; loop" style="aspect-ratio: 1.33333 / 1"></iframe>

<iframe title="Blender Abstract Torus" 
src="https://www.youtube.com/embed/JTrQWg8KnNU?autoplay=1&showinfo=0&playlist=JTrQWg8KnNU&loop=1" height="200" width="300" allowfullscreen="" allow="fullscreen; loop" style="aspect-ratio: 1.33333 / 1"></iframe>

With Atom, Default and other themes it looks as follows:

With Minimal theme turned ON it looks as follows (all iFrames are 100% wide, width parameter is ignored):

With Minimal Theme Settings:

what is wrong?
