Can't update product group bids.

SDK Version: v13.0.14

The following (simplified) code:

$updateProductGroupBids = new ApplyProductPartitionActionsRequest();
$updateProductGroupBids->CriterionActions = [];
$action = new AdGroupCriterionAction();
$action->Action = ItemAction::Update;
$action->AdGroupCriterion = new BiddableAdGroupCriterion();
$action->AdGroupCriterion->AdGroupId = $adGroupId;
$action->AdGroupCriterion->Id = $criterionId;
$action->AdGroupCriterion->CriterionBid = new FixedBid();
$action->AdGroupCriterion->CriterionBid->Amount = $bid;
$updateProductGroupBids->CriterionActions[] = $action;

$soap->ApplyProductPartitionActions($updateProductGroupBids);

Generates this SOAP request:

That doesn't look right. The bid amount isn't even included in the XML. The docs say the request should be different.

https://learn.microsoft.com/en-us/advertising/campaign-management-service/adgroupcriterion?view=bingads-13#remarks

If you generate the SOAP manually, use the type attribute of the node as shown in the following example, to specify the type of criterion.
<AdGroupCriterion i:type="BiddableAdGroupCriterion" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Id i:nil="true" />
<Status i:nil="true" />
. . .
</AdGroupCriterion>

Got this generic response, btw:

Looks like the SDK isn't encoding this request correctly. I tried some SoapVar hackery to inject custom XML to make it conform to the spec, but couldn't nail it down.
