[MaterialButton] maxLines does not work with 99% of inputType

[adrianvintu]

Description:

I want to display a MaterialButton containing a multi line string, formatted as android:inputType="textCapSentences".

The text is not rendered multi line, only single line. Even though android:maxLines="10" is set.

This android:inputType="textMultiLine" works, but this android:inputType="textMultiLine|textCapSentences" will ignore textCapSentences. Other inputTypes are ignored as well.

Expected behavior:

The text in the button is rendered multi line, while formatting as textCapSentences.

Workaround:
Set max lines in code.

This btn.setMaxLines(10) renders multiline, with textCapSentences formatting. But not if maxLines only set in XML.

Source code:

<com.google.android.material.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="textCapSentences"
android:maxLines="10"
android:text="test\nmultiple\lines" />

Android API version:
21+
