2019.3.1 fails to back-indent braces

Annoyingly, 2019.3.1 made the Java editor refuse to back-indent braces for me in the way that IDEA has always worked (for me, at least). For example, I start with:

if( VERBOSE )
{
  System.out.println( "Finished product:\n" + conceptProduct );
  System.out.println( "POJOs found in parsing:" );
  for( Pojo pojo : pojoList )
    System.out.println( PojoFactory.toString( pojo ) );
}

If I bracket the last three lines to control them with another variable in my unit test case, nothing happens when I type the closing brace:

if( VERBOSE )
{
  System.out.println( "Finished product:\n" + conceptProduct );
  if( DEEP_VERBOSE )     // add this line
  {                      // then this line
  System.out.println( "POJOs found in parsing:" );
  for( Pojo pojo : pojoList )
    System.out.println( PojoFactory.toString( pojo ) );
  }                      // then this closing brace
}

Historically, back to IDEA 12 or so when I began using IntelliJ, Adding the brace should have resulted in transforming the part of the paragraph I'm changing to

if( VERBOSE )
{
  System.out.println( "Finished product:\n" + conceptProduct );
  if( DEEP_VERBOSE )
  {
    System.out.println( "POJOs found in parsing:" );
    for( Pojo pojo : pojoList )
      System.out.println( PojoFactory.toString( pojo ) );
  }
}

I have changed no settings for Java indentation, etc. (for years) since I created my own (Allman) indentation for IDEA to follow. This is the first update to ignore me.

Yes, I have highlighted (selected) the subblock of code above and asked IDEA to reformat it, but it does nothing.
