Undesired hyphens in word-break context

[Niels]

In Flare 2017 r3 we have defined codebox styles (based on "div" with "p" in one use case and "pre" in another) for long sections of XML code in PDF print output. Ideally I would like to deactivate any auto insertion of hyphens and we do not mind having words break anywhere inside. However, attempts to achieve this by a style setting show no effect, such as using "hyphens: none;", e.g.:

div.codebox {... hyphens: none; ...}

Can there be any CSS rules in conflict here, or is this just not supported, or is there any foolproof alternative to get rid of hyphens?

Rationale & related bug
We want to make sure that correct XML syntax is documented and in particular there is the related bug 119499 (see: viewtopic.php?f=10&t=20557&p=124130&hil ... ns#p125865) where single letters are duplicated after a hyphen in PDF output.

Found solutions with the help of the MadCap Flare CSS style guide (FlareStylesGuide.pdf):

• use property "mc-hyphenate = never" (listed among "Show all properties > Unclassified")
• apply this via a complex selector (e.g. on div/p style such as div.codebox > p style)
• apply this directly on a style (e.g. a preformatted "pre.codebox")
