DCPathItemButtons become unclickable

[TheKongBakPau]

I am using a UITabBarController with a DCPathButton as the centre button. One of my tabs consists of a UIWebView. I have found that when on this tab, after I press on something in the web view that triggers some javascript to be executed, that afterwards the DCPathItemButtons become unresponsive. Pressing the DCPathButton still displays them correctly, I just can no longer press on them. I can still press elsewhere and they disappear back again, just nothing happens when I press on the DCPathItemButtons. It acts as it no longer has a delegate, but stepping through it tells me it still has, but

func

pathButton(_ dcPathButton: DCPathButton!, clickItemButtonAt itemButtonIndex: UInt)

is no longer invoked. Any help would be greatly appreciated.

@TheKongBakPau If you use the view debugger are the buttons the topmost view? Or are they covered by another view?
