Svelte: Class directive on IE 11 and older browsers

Created on 12 Sep 2018  路  5Comments  路  Source: sveltejs/svelte

< IE 11 and some older browsers support classList methods but don't support the .toggle() second boolean argument, resulting in erroneous behavior.

Maybe we could add a legacy alternative?

I know the polyfill solves this issue. I'm just bringing this here to see if it's something that the legacy flag should support 馃榿

The polyfill does actually fill in the missing functionality with the second argument https://github.com/yola/classlist-polyfill/blob/master/src/index.js#L222
