Type error when using fallbacks array with typescript

[paul0lden]

Expected behavior: Fallbacks array with typescript styles

Describe the bug: Using fallbacks array in style object with typescript leads to an error. If I'm using fallbacks as an object it works just fine. Also the style compiles successfully, but the typerror may lead to the pipeline fails and other messy things.

Type '{ width: string; }[]' is not assignable to type 'JssValue | JssStyle<any, undefined> | Observable<JssValue | JssStyle<any, undefined> | undefined> | ((data: any) => JssValue | ... 1 more ... | undefined)'. Type '{ width: string; }[]' is not assignable to type '(string | number | (string | number)[])[]'. Type '{ width: string; }' is not assignable to type 'string | number | (string | number)[]'. Object literal may only specify known properties, and 'width' does not exist in type '(string | number)[]'.ts(2322)

I still have the same issue on version 10.9.0, even though it's over a year old. Do you happen to have any updates on this?
