Error thrown from class attribute with trailing whitespace

[dkrasner]

When the class attribute string contains a trailing whitespace the following error is thrown in console:

maquette.umd.js:291 Uncaught DOMException: Failed to execute 'toggle' on 'DOMTokenList': The token provided must not be empty.

This looks to be related to a closed issue but the problem persists.

Here is a codepen example. Changing textcolor textsize to textcolor textsize (note the trailing whitespace) will throw the above error in console.

Sorry about the late reply (there was an issue with our chat application integration).

The issue is fixed and shipped in 3.3.4
