Custom style properties prevent MQ from rendering components

[JordanMcInnisGithub]

As per title, mithril query fails to render components that are passed custom style properties via mithril js syntax. For instance, declaring a component with mq such as:

const someComp = mq(someComp, { attr1: true, attr2: false, style: {"--testVar": 12}});

or within the component view such as:

return m("some-name", { style: { "--testVar": 12}}, [childrenHere...]);

...will cause the following error when running tests

TypeError: Cannot read properties of undefined (reading 'type')

However, setting up the same functionality in the same way, but adding the properties via js inside the component view()/oncreate() causes no issues.

document.querySelector(".someComp").style.setProperty("--testVar", 12);
