Blazor touch/mouse event question

[Phexyaa]

I am working on an app that can be used on either desktop or mobile and I would like touch events to perform the same duties as mouse events to avoid repetition.
I started by reading this (section 7), and was wondering if Blazor supports touch events as specified?
Right now I have an svg element with @onmousedown defined that works with mouse events, but does not fire on touch as the spec would make me believe per the note in this section.

Edit:
Forgive me, I'm still learning web development. I forgot that multiple browsers were a thing.
The mouse events fire fine with touches when using chrome on mobile, but do not fire when using Firefox. I've came across other similar issues that were a result of Firefox wanting a specific event name (onwheel vs onmousewheel), could this be something similar?
