Thank you for that, very illustrative. That is a very odd problem.
The only thing I can think is that there's something up with your code, if not, then you've found a system bug. You seem to be missing quotation marks around the values in the options, and the select doesn't have a closing tag, can you try replacing part of the code with this:
<select id="archive-pages" onchange="window.open ( this.value, '_self' );">
<option value="#">
WORK
</option>
<option value="/popeyesclw">
Popeyes - Crunchy Little Weirdos
</option>
<option value="/seattle-kraken-fear-the-deep">
Seattle Kraken - Fear the Deep
</option>
<option value="/popeyessocial">
Popeyes Social
</option>
<option value="/minutemaid">
Minute Maid - Refreshing Bumpers
</option>
<option value="/mercury-insurance">
Mercury Insurance - Out of Home
</option>
<option value="/nypostspecwork">
Spec Work - NY Post
</option>
<option value="/about-ozzie">
ozzie nunez
</option>
</select>
Let me know if that has any impact.
