The problem is that there is an inconsistency with the escaping of regular
strings vs. LazyT objects when serializing HTML helpers. When helpers are
serialized, all attribute values are passed to gluon.html.xmlescape. In
xmlescape, regular strings are ultimately passed to cgi.escape with the
"quote" argument set to True. However, LazyT objects are not passed to
cgi.escape but instead have their .xml() method called, and that method
calls cgi.escape with the "quote" argument set to False. As a result,
double quotes are not converted to """. This creates a problem because
when helpers are serialized, all attributes are wrapped with double quotes,
so you cannot have double quotes within the attribute unless they are HTML
encoded. This should probably be considered a bug. Perhaps xmlescape should
check for LazyT objects and instead of calling the .xml() method, treat it
as a string object.
For now, the workaround is to force the conversion of the LazyT object to a
string before passing it as a helper attribute:
textarea = TEXTAREA(_placeholder=str(my_text), ...)
Maybe submit a github issue about this and link to this post.
