Button and the title attribute usage

[stevegreco]

I am looking for guidance around the usage of the title attribute on the Button component and why that is not something that is supported and if there is any workaround to allow it to be passed through.

My initial thought and looking through some old issues seems to point to the fact that it is just inconsistent and provides very lackluster accessibility, especially for keyboard users.

Just looking for some insight, as we have had some of our users ask about this. One of the main arguments against using the Tooltip has been bad performance when rendering a larger list of items that all have their own Tooltip being rendered.

Thanks, this sounds reasonable, however, I'd like some more information about the bad performance. Bad how? time to render the large list? time to open a tooltip? Do you have an example in a stackblitz or codesandbox?
Hopefully we can address that so that you don't need to use a "lackluster" experience.
