#TEXT handler not called for text that precedes an element

[chrispitude]

In this testcase, I have elements inside text blocks:

<ul>
 <li>This is <?Fm Condstart _COND4_?>item 1.</li>
 <li>This is <b>boldfaced</b> text in item 2.</li>
</ul>

I define a handler to wrap all #TEXT blocks in <TEXT> elements:

'#TEXT' => sub { $_->wrap_in('TEXT'); return 1; }

In the resulting twig, I see that the handler is called for text that follows the bisecting elements, but not before (both "This is" strings):

<ul>
  <li>This is <?Fm Condstart _COND4_?><TEXT>item 1.</TEXT></li>
  <li>This is <b><TEXT>boldfaced</TEXT></b><TEXT> text in item 2.</TEXT></li>
</ul>

Testcase:

#!/usr/bin/perl
use strict;
use warnings;
use XML::Twig;

my $xml = <<EOF;
<ul>
 <li>This is <?Fm Condstart _COND4_?>item 1.</li>
 <li>This is <b>boldfaced</b> text in item 2.</li>
</ul>
EOF

my $twig = XML::Twig->new(
 pi => 'process',
 twig_handlers => {
  '#TEXT' => sub { $_->wrap_in('TEXT'); return 1; },
  },
 )->parse($xml);

$twig->print(pretty_print => 'indented');
