Incorrect TextField inline-icon alignment

[Flamesson]

Sample project: https://github.com/izumi-jmix/icon-and-font-size

Steps to reproduce:

1. Change caption position of a
   , like:

<form id="form" dataContainer="userDc" captionPosition="TOP">

2. Add a <textField>, bound it to a property. Also add an icon and "inline-icon" stylename, like:

<textField id="usernameField" property="username" editable="false" 
           icon="CHECK_CIRCLE" stylename="inline-icon"/>

3. Change size at theme settings to "Small", or, at least "Medium".

4. Bug sample:

Notes:

• Margin-top of icon is not scaled, depending on theme-size. Probably it is the source of the problem.
