Khazix recall bug [Gameplay]

I've encountered a bug over the last month or so where at times when playing Khazix I press B to recall and it then cancels. I've had this happen numerous times. I press B, then the recall briefly begins, then I open the shop or move the camera away from myself to watch something else only to find i'm no longer recalling. I only realise I've not recalled when I look back to my champion and i'm just sitting there not moving. I'm unsure if this bug occurs when you open the shop, or if it just cancels regardless of what you do.
