[MaterialButton] Seemingly benign exception log spam instantiating MaterialButton since 1.14.0-alpha09

[bubbleguuum]

Since I updated from alpha08 to alpha09 I noticed this logcat exception spam inflating any MaterialButton:

Failed to inflate ColorStateList, leaving it to the framework

It is caused by the new attributes added in the "Add support for a secondary icon" commits.
It doesn't seems to have any ill effect (app is not crashing or anything) but I thought I would mention it in case it is a problem.

I got the same with ExtendedFloatingActionButton

Dan do you know what can possibly cause this?

As an extra note:
These logs are first visible after I clicked at my ExtendedFloatingActionButton.

After more digging, here's some observations:

secondaryIconTint has been added to Widget.Material3.Button:

material-components-android/lib/java/com/google/android/material/button/res/values/styles.xml

Line 647 in 4bb9acd

<item name="secondaryIconTint">@color/m3_button_foreground_color_selector</item>

But not all buttons styles extend Widget.Material3.Button so the secondaryIconTint attribute will be missing for them.
For example Widget.Material3.Button.TextButton extends Widget.MaterialComponents.Button.TextButton. There might be other button styles that do not extend Widget.Material3.Button.TextButton and for which secondaryIconTint must be added.

Edit: seems to only be Widget.Material3.Button.TextButton missing the attribute, but need to be checked.
