[CDK-8.0.0-beta][Drag&Drop] set new position isn't working

[MDzyga]

What is the expected behavior?

Set new position using new version of SDK.

What is the current behavior?

Nothing happened.

What are the steps to reproduce?

My HTML looks like:

<div class="background-image"
   [ngStyle]="getBackground()">
<img #layout="cdkDrag"
    cdkDragBoundary=".background-image"
    cdkDrag
    (cdkDragEnded)="dragMoved()"
    [cdkDragFreeDragPosition]="currentPosition"
    class="qr-code-image"
    [style.width.px]="qrCodeWidth"
    src="{{baseUrl}}images/qr-code.png"
    alt="QR Code">
</div>
     ....
      <mat-form-field>
        <input #positionX
               matInput
               placeholder="Position X"
               type="number"
               min="0"
               [max]="maxPositionX"
               matTooltip="Move from left"
               [ngModel]="qrCodeImage.qrCodeX"
               (ngModelChange)="changePosition($event, 'qrCodeX')"
               name="qrCodeX">
      </mat-form-field>

      <mat-form-field>
        <input #positionY
               matInput
               placeholder="Position Y"
               type="number"
               min="0"
               [max]="maxPositionY"
               matTooltip="Move from top"
               [ngModel]="qrCodeImage.qrCodeY"
               (ngModelChange)="changePosition($event, 'qrCodeY')"
               name="qrCodeY">
      </mat-form-field>

In my typescript file I have below method to set X and Y position

changePosition(positionValue: number, changedPropertyName: string) {
    this.qrCodeImage[changedPropertyName] = positionValue;

    this.currentPosition = { x: this.qrCodeImage.qrCodeX, y: this.qrCodeImage.qrCodeY };
}

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

"@angular/animations": "^7.2.12",
"@angular/cdk": "^8.0.0-beta.0",
"@angular/common": "^7.2.12",
"@angular/compiler": "^7.2.12",
"@angular/core": "^7.2.12",
"@angular/forms": "^7.2.12",
"@angular/material": "^8.0.0-beta.0",
"@angular/platform-browser": "^7.2.12",
"@angular/platform-browser-dynamic": "^7.2.12",
"typescript": "~3.2.4",

Is there anything else we should know?

When I change image's initial size, drag & drop "thinks" that image have old size. Because of it I can move some part of it out of the area.
