Wrong data passed into custom renderer in 2.9.x

Expected Behavior

Expected behavior as it was in Chart.js 2.8.x.
draw method in my applyCustomRenderer should get correct data in this._model.x and this._model.width.
See values in the console in following codepen, there are correct float values.

Context

Trying to render rounded corner bars like this (version 2.8.0):

With version 2.9.x I am unable to render these rounded bars because of NaN values in this._model.x and this._model.width. No bars are being rendered at all.

Environment

• Chart.js version: 2.9.x
• Browser name and version: All browsers
