alert() prior first textbox() doesn't show any text

[htgoebel]

If there has not been any textbox (or such) displayed prior to the first alert, the alert will not show any text.

Here is a simple aroma-config to show the effect:

fontresload( "0", "ttf/Roboto-Regular.ttf;ttf/DroidSansFallback.ttf;", "12" );
fontresload( "1", "ttf/Roboto-Regular.ttf;ttf/DroidSansFallback.ttf;", "14" );

alert("Alert 1", "This is an Alert 1");
textbox("Welcome", "You are welcome", "", "");
alert("Alert 2", "This is an Alert 2");

The first alert will display not text, but the second one will.
