height, verticalAlignment doesn't work
i create a textLayer in such code which set stringValue, verticalAlignment, frame and so on in sketch 52.6
```js
var Text = require('sketch/dom').Text;
var layerObjectJS = new Text({
            parent: currentLayer.parentArtboard(),
            text: "123",
            name: "123",
            fixedWidth: 1,
           alignment:2,
           frame:{x: 10,  y:10, width:145, height:145}
           });
var layerObject = layerObjectJS._object;
layerObject.textColor = MSImmutableColor.colorWithSVGString("#0000FF");

        //set paragraph
            var paragraphStyle = layerObject.paragraphStyle();
            paragraphStyle.setParagraphSpacing("3");
            layerObject.addAttribute_value("NSParagraphStyle", paragraphStyle);

        //set font
        var newFont = NSFont.fontWithName_size("PingFangSC-Regular", 30);
        layerObject.setFont(newFont);

        layerObject.setKerning(2);
      layerObject.verticalAlignment = 2;
```
since i want make the text height of 90 but it result to 42 which just wrap the text

the i use
```js
currentLayer.absoluteRect().height = 90;
```
the height of layer is 90 but the verticalAlignment is wrong, and can't be edit otherwise you change the height of layer manual not by code

it seem that when the height of layer is bigger than the text, verticalAlignment can not work
