Does Phaser 2 cache webfont texts as textures?

I'm working with 2.6.2 and drawing some webfonts directly instead of bitmap fonts.

I know rendering a vectorial font is an expensive operation and I was thinking of just rendering it to a separate BitmapData and then use the BitmapData as an image instead, but since Phaser 1 performance on text rendering seems to have improved a lot, so I was wondering if these optimizations are maybe already done behind the scenes by Phaser, but didn't find anything on the source code so far.

Does anybody know?
