<!--
The floats (inc. padding) are 7ch wide, and occupy ~2 lines,
so without balancing, layout would be
    +--------------------------+
    | FLOAT abcde fghi jklm nop|
    | FLOAT qrst uvw     FLOAT |
    |xyx!                FLOAT |
    +--------------------------+

Applying text-wrap:balance results in
    +--------------------------+
    | FLOAT abcde fghi         |
    | FLOAT jklm nop     FLOAT |
    |qrst uvw xyx!       FLOAT |
