CanvasHTML5 TextInput Component font size issue

Animate CC 2017 Version 16.0.1

MacOS Sierra Version 10.12.1

MacBook Pro Retina 15inch, Late 2013

Working with the TextInput components (creating a form) for a CanvasHTML5 project.

The stage is 1366x768

Publish settings:

Center stage - Horizontally

Make responsive - By width

Scale to fill - Stretch to fit

Successfully controlling the input width and input font sizes as the browser scales using CSS breakpoints.

Looks good on the phones/tablets I'm testing. Looks good on Mac and scales nicely with the browser.

However, on a PC laptop (1366.x768), the fonts are probably 1.5 times larger. (I checked 2 different PCs and they looked the same)

Anyone know why that would be? Am I doing something wrong?

The form is its own movie clip. The TextInput components are each on their own layer inside the form movie clip.
