Warning: Found 2 elements with non-unique id #null

[illright]

TextFields and other components that have the id as a prop default to that ID being null for some reason, which is the reason of warnings in the console like:

Found 2 elements with non-unique id #null

This seems to be an issue with Sapper's rendering (though I couldn't find any related open issue on their repo). This is because if I navigate to https://illright.github.io/attractions/docs/components/text-field by first going to https://illright.github.io/attractions/docs/ and then clicking on "TextField", I don't get this error. Even when going to that page directly, the null id is only present in the page source (CTRL + U), but not actually on the element if you inspect it through the DevTools.

Yeah, when I investigated, I also came to the conclusion that Sapper renders out the null-valued props and Svelte removes them afterwards. Been meaning to create an MCVE and open an issue to Sapper
