I wish I could fix this, but I found several places to fix this, such as patchProp,patchDOMProp, or VueElement's _resolveDef method, and I need a good suggestion

[hcg1023]

@LinusBorg Actually, WHAT I mean is that I want to develop and fix this problem by myself. I think it is most appropriate to modify it in the method resolveDef. I wonder if you can assign this task to me?

Hi @hcg1023

sure, you can work on this. I just assigned myself to remember to leave the suggestions you asked for.

I'm still thinking about this a bit in the context of not just custom elements but the assignment of element properties as a whole. Will get back to you shortly.

@LinusBorg Ok, looking forward to your reply, I will do this based on your reply

I saw this in the documentation and felt like it didn't work when it was precompiled

This is expected behavior. When you use .xx shorthand or the .prop modifier, the key will be used as-is without any modification. You are expressing the intention to set the prop as a DOM property with the exact key.

If you are using it in DOM templates, .camel modifier will be needed.
