Title: If svg has been given a min-width, it must be reset to none.

Other objects there are likely also reliant on 'min-width: none'. If that's not the case, the scope of this can be minimized, but "reset"-type css that is required needs to be clearly declared or else it will be overridden by external stylesheets.
