At HEAD, after D15396, workboards break because the "Points" tag isn't where the JS expects it to be. Here's a minimal fix:

diff --git a/src/view/phui/PHUIHeaderView.php b/src/view/phui/PHUIHeaderView.php
index 0e76aaf..c274bc7 100644

-    if ($this->properties || $this->policyObject) {
+    if ($this->properties || $this->policyObject || $this->tags) {
       $property_list = array();
       foreach ($this->properties as $type => $property) {
         switch ($type) {

This fixes things, but the rendering in the UI is a little funny, so maybe we don't want to do that:

The specific error is:

Error: JX.DOM.find(<node>, "span", "column-points"): matched no nodes.

That's coming out of this in WorkboardColumn.js:

this._pointsNode = JX.DOM.find(this._panel, 'span', 'column-points');

That should be pretty flexible about changes, but a possible fix might involve adjusting it.

Local repro is probably:

• Enable "points" field.
• View any workboard which you expect to have cards.
• Check console for error / see no points node in DOM.

(This repros for me locally.)

This is only in master so not a big deal, HEAD of stable is fine.
