When modifying and saving $doc in a script macro the second script macro ends up with the unmodified version of $doc

To reproduce:

• create a document with the following content:

{{velocity}}
#set ($titleDate = $datetool.date)
$doc.setTitle("$titleDate")
$doc.save()
{{/velocity}}

{{velocity}}
Expected title: $titleDate
Title in \$doc: $doc.title
{{/velocity}}

-> the display actually show the version before the modification and the save instead of the current state of the document

Paradoxically, if the document is *not* saved, then the second macros end up with the modified version of $doc.
