Word spacing incorrect for different text styles

[abeverley]

The spacing for words is defined based on the default font. So if a different size font is used for a different style, that style inherits the word-spacing for the smaller font in the default style. This happens in apply() withe the code my $space_width = $content_text->advancewidth(' ');

Note: I have worked around this in my application (using CtrlO::PDF) so I am really just opening the issue here for the record.
