Some wordwrapped text renders incorrectly in firefox

[Aguacero]

I have encountered very strange firefox way of multi-line text rendering.
Some of the text appears like it has minimal line-height, while other text sprites render normally (see attachment)
And if user reloads page - everything start working just fine, but still works wrong if user restarts firefox and then loads page.

I can't see any significant difference between right and wrong rendered texts in the way I create text sprites.

Had anyone experienced something like this? Any ideas how to fix it?

Code for the badly rendered sprite: 

this.dialogPhrase = this.game.add.text(90, this.game.height - 110, dialog.text, {

font: '18px Russo One',

fill: '#222222',

wordWrap: true,

wordWrapWidth: 820

});

Code for the well rendered sprite:

const nextMenuItem = this.game.add.text(682, nextY, item.text, {

font: '16px Russo One',

fill: '#222222',

wordWrap: true,

wordWrapWidth: 280

});

I see same bug in Firefox 55

Кстати, тоже с кириллицей! )

Anybody knows what is problem?  Phaser 2.10.1

I try to work around with splitting into standalone lines
