A lot of guesses, by me and ++bliako: no resolution.
I was tempted to raise as doco/bug issue:
the current target being "Active bugs for Tk",
but that is shutting down in a couple of days.
I'll wait and see what happens.
I'm still using this function.
I did determine a number of things.
Two things of note:
-
An update of the UI ($mw->update) is entirely unecesssary;
an update is necessary, but only of the canvas ($canvas->update()).
-
Depending on your use case, you may be able to exploit the ability to
compose individual items, as well as groups, into a single group.
I found this to be useful, YMMV.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
