Thank you for your contribution. Maybe we should review https://github.com/vuejs/core/pull/10977 first. If the author is no longer active, we can consider creating a new PR.

is there any work around for using popover when using jsx syntax. currently its impossible to use popover with error Found a 'popover' attribute with an invalid value.

I would also like to use this :)

Maybe the jsx.d.ts should be reconsidered long-term to borrow from TypeScript's lib.dom.d.ts, but I imagine that would be... non-trivlal.

In the mean time, adding a html-attributes.d.ts file like this to my repo seems to work:

// Extend Vue's HTML attributes to include modern HTML attributes that TypeScript doesn't recognize yet

// TODO: Get rid of this file when Vue 3 includes popover attributes in its types.
// https://github.com/vuejs/core/pull/13113

declare module '@vue/runtime-dom' {
  interface HTMLAttributes {
    // Popover API attributes
    popover?: 'auto' | 'manual' | 'hint';
    popovertarget?: string;
    popovertargetaction?: 'show' | 'hide' | 'toggle';
  }
}

// For Vue 2.7 compatibility
declare module 'vue' {
  interface HTMLAttributes {
    // Popover API attributes
    popover?: 'auto' | 'manual' | 'hint';
    popovertarget?: string;
    popovertargetaction?: 'show' | 'hide' | 'toggle';
  }
}

export {};
