It may be that one or two (or one or two hundred?) authors have requested this
change but the existing rules are based on decades of experience of negative
effects of having a system where white space wrapping is generally harmless but
line breaks are preserved in a few contexts. If this change (which is
incompatble with html4, html5-xhtml and any other XML or  SGML usage) is made
then bad linebreaks will inevitably end up in tooltips as files are reflowed in
It is better not to add the bad behaviour than add it and then add text to the
specification warning of the dangers. Especially as the existing text does not
even say that it is not compatible with one of the supported serialisations or
with legacy behaviour.

suggested tracker title

   line breaks in attributes

suggested text

white space normalisation should be applied to attribute values, consistent
with html4 and xml. To insert a linebreak into an attribute value a character
reference should be used such as &#10;
