textarea's maxRows is of no effect

[linuxyf]

i want a textareafield to show 20 lines text, so i set the maxRows: 20, but only 4 lines text is visible. the code is as following:

app.js

Ext.Loader.setConfig({ enabled: true});


Ext.application({
    name: "Test",
    
    views:[
		'Single'
    ],
    
    launch: function() {
        Ext.create('TestDriver.view.Single');
    }
});

Single.js

Ext.define('Test.view.Single', {
    extend: 'Ext.form.Panel',
    xtype: 'single',
    
    requires: [
		'Ext.form.FieldSet'
    ],


    config: {
		fullscreen: true,
		layout: 'fit',
		items: [
		{
			xtype: 'fieldset',
			layout: 'vbox',
			labelAlign: 'left',
                        labelWidth: '40%',
			items:[{
				xtype:	'textareafield',
				id:		'textarearequestdata',
				maxRows: 20,
				cls:	'TextAreaBorder'
			}]
		}]
    }
});

This was a bug that should be fixed in Beta 3.

Very strange. This was definitely fixed, but somehow the code got removed. Sorry about that!

Here is a quick override to fix the issue for now:

Ext.define('Ext.overrides.field.InputMaxRows', {
    overrides: 'Ext.field.Input',

    applyMaxRows: function(maxRows) {
        if (maxRows !== null && typeof maxRows !== 'number') {
            throw new Error("Ext.field.Input: [applyMaxRows] trying to pass a value which is not a number");
        }

        return maxRows;
    }
});

This post is 4 years old and still "maxRows" has no effects! I use a TextArea with maxRows=2 and I get one with rows=4 fixed! Any solution? The fix above did not work. I am on Sencha ExtJS 6 modern.
