fontsize_formats does not respect font sizes in "em" units.

This is a buh report.

I have this option for TinyMCE: fontsize_formats: "0.7em 0.8em 0.9em 1em 1.2em 1.5em 1.9em 2.4em"

And these sizes do not work. So I searched why and found this code in tinymce.js:

  var fromFontSizeNumber = function (editor, value) {
    var fontSizeNumber = parseInt(value, 10);
    if (fontSizeNumber >= 1 && fontSizeNumber <= 7) {
      var fontSizes = $_6msxiw2jjfuw8lkv.getFontStyleValues(editor);
      var fontClasses = $_6msxiw2jjfuw8lkv.getFontSizeClasses(editor);
      if (fontClasses) {
        return fontClasses[fontSizeNumber - 1] || value;
      } else {
        return fontSizes[fontSizeNumber - 1] || value;
      }
    } else {
      return value;
    }
  };

As you can see, the TinyMCE code uses the integer part of each font size, which is wrong since I specify font sizes in a relative manner (using “em” units). So it replaces the values with “xx-small” and so on.

The expected behavior is to respect values which are specified in “em” units. Test if the value is ending with an “em” and in that case immediately return that.

TinyMCE 4.7.11, Windows 10 x64, Firefox (latest).

Is this Issue getting any updates?

Also I could mention that there is a lack of “font-size” removal option. Like with font color box, which includes a possibility to remove the applied color. The same would be useful for font-sizes. It should include some kind of “select default” option or “dash” option. Or at least a possibility to select the same option from dropdown to cancel the selection. Because - once I selected the font size, I cannot unselect it. I can only remove the whole formatting.
