MetricAffectingSpan Android Studio Preview Bug

This project implements a reproducable case for a bug report I created for Android Studio.

Expected Behavior:

Andriod studio renders a custom textview which adds MetricAffectingSpans to the text it is given via setText(CharSequence, BufferType) with correct wrapping and no clipping/truncating.

Actual Behavior:

Andriod Studio's layout preview incorrectly inserts line breaks into the text when rendering the custom text views.

Screenshots:

These screenshots show several instances of MyTextView:

  1. Half the text is rendered with a ForegroundColorSpan (non-metric affecting, works fine in the android studio preview.
  2. Half the text with a monospace TypefaceSpan (metric affecting, incorrect in preview)
  3. Half the text with an AbsoluteSizeSpan (metric affecting, incorrect in preview)
  4. Half the text with a RelativeSizeSpan (metric affecting, incorrect in preview)
  5. Half the text with a ScaleXSpan (metric affecting, incorrect in preview)
  6. Half the text with a SubscriptSpan (metric affecting, incorrect in preview)
  7. Half the text with a SuperscriptSpan (metric affecting, incorrect in preview)
