[FloatingActionButton] App crashes because of shapeAppearance on FAB

Description: Here is the Demo app https://github.com/ashraf-patel/MaterialComponentsDemo, as described in this link to the gif you can reproduce the crash.

Expected behavior: It should not crash.

Source code:

Here is the problem, making cornerSizeTopRight and cornerSizeBottomLeft to 30dp is causing the crash. link to the Gif

<style name="ShapeAppearance.Sunflower.FAB" parent="ShapeAppearance.MaterialComponents">
        <item name="cornerFamily">rounded</item>
        <item name="cornerSizeTopLeft">0dp</item>
        <item name="cornerSizeTopRight">30dp</item>
        <item name="cornerSizeBottomRight">0dp</item>
        <item name="cornerSizeBottomLeft">30dp</item>
</style>

Below code works link to the gif

<style name="ShapeAppearance.Sunflower.FAB" parent="ShapeAppearance.MaterialComponents">
        <item name="cornerFamily">rounded</item>
        <item name="cornerSizeTopLeft">0dp</item>
        <item name="cornerSizeTopRight">0dp</item>
        <item name="cornerSizeBottomRight">0dp</item>
        <item name="cornerSizeBottomLeft">0dp</item>
</style>

My bad the corner can be more than 50% since the other one on the same side is 0.

@gabrielemariotti It repros in 26.

I’ll have to debug this tomorrow setting app:shapeAppearanceOverlay=“@null” seems to help, which doesn’t make sense to me since the ShapeAppearance in the example is setting the more specific cornerSizes. The default fab overlay only sets app:cornerSize to 50% the shape appearance should ignore the overlay in this case.
