**Overview:**
The size and text of button in Android will be larger than the normal button if user defined ButtonRenderer is used.

**Steps to Reproduce:**
You can use my Code on https://github.com/maxchu92/Xamarin.Forms-Button-Renderer-Bug
1. Create a new Portable project with Xamarin.Forms v2.3.0.107
2. Apply Material Theme and FormsAppCompatActivity to Android.
3. Create a page with buttons
4. Create an empty ButtonRenderer

**Actual Results:**
The size and text of the button is incorrect even if nothing is defined in ButtonRenderer.

**Expected Results:**
Button should displayed as the same as button without using user defined ButtonRenderer

**Build Date & Platform:**

- Android 4.4.4


**Additional Information:**
- Tested on Xamarin.Forms v2.3.0.107 & v2.1.0.6529
- Used Material AppCompat Theme

You probably shouldn't compare different texts. Android might be doing auto-resizing to fit contents within the bounding region. When I ran your repro with "CustomButton" or "Button" on all four buttons, everything looked the same.
