text cut on Firefox when changing the anchor point

[Enriqueto]

Phaser CE v2.11.1
Firefox v64.0 on mac

when doing this:

this.ballsCounter.anchor.y = .5;
this.ballsCounter.setShadow(2, 2, "rgba(0,0,0,0.5)", 3);
this.ballsCounter.stroke = "#000000";
this.ballsCounter.strokeThickness = 2;

the text is cut on Firefox (see picture). In Chrome it's rendered correctly.
