DOMXPath multiple contain selectors not working - dom

Question

I have the following XPath query that a kind user on SO helped me with:
$xpath->query(".//*[not(self::textarea or self::select or self::input) and contains(., '{{{')]/text()") as $node)
Its purpose is to replace certain placeholders with a value, and correctly catches occurences such as the below that should not be replaced:
<textarea id="testtextarea" name="testtextarea">{{{variable:test}}}</textarea>
And replaces correctly occurrences like this:
<div>{{{variable:test}}}</div>
Now I want to exclude elements that are of type <div> that contain the class name note-editable in that query, e.g., <div class="note-editable mayhaveanotherclasstoo">, in addition to textareas, selects or inputs.
I have tried:
$xpath->query(".//*[not(self::textarea or self::select or self::input) and not(contains(#class, 'note-editable')) and contains(., '{{{')]/text()") as $node)
and:
$xpath->query(".//*[not(self::textarea or self::select or self::input or contains(#class, 'note-editable')) and contains(., '{{{')]/text()") as $node)
I have followed the advice on some questions similar to this: PHP xpath contains class and does not contain class, and I do not get PHP errors, but the note-editable <div> tags are still having their placeholders replaced.
Any idea what's wrong with my attempted queries?
EDIT
Minimum reproducible DOM sample:
<div class="note-editing-area">
<textarea class="note-codable"></textarea>
<div class="note-editable panel-body" contenteditable="true" style="height: 350px;">{{{variable:system_url}}</div>
</div>
Code that does the replacement:
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML($html);
$xpath = new DOMXpath($dom);
foreach ($xpath->query(".//*[not(self::textarea or self::select or self::input or self::div[contains(#class,'note-editable')]) and contains(., '{{{')]/text()") as $node) {
$node->nodeValue = preg_replace_callback('~{{{([^:]+):([^}]+)}}}~', function($m) use ($placeholders) {
return $placeholders[$m[1]][$m[2]] ?? '';
},
$node->nodeValue);
}
$html = $dom->saveHTML();
echo html_entity_decode($html);

Use this below xpath.
.//*[not(self::textarea or self::select or self::input or self::div[contains(#class,'note-editable')]) and contains(., '{{{')]
