Input stops worksing on IOS

Hi there,

This is somewhat random but I only observed on IOS. I have the following listener

this.input.on('pointerup', this.moveBall, this);  

However, the input.pointer1.active is sometimes stuck at true and after that point, the input does not respond to any other interaction.

The way I can replicate is basically on an iPhone browser. I slightly move the browser down but without getting to the point that the browser calls its refresh.

However, this happens on my actual production game randomly. There is a similar bug report on phaser CE but I wanted to check if someone knows a workaround.

Thanks,

Doug
