Weird textinput behavior embedded font

Question

I have this weird behavior with an embedded font in a textinput.
I have embedded the myriad font and aplied it on a textinput.
In this weird scenrio when i type "test configuration" in the textinput and then pres the left arrow key the cursors will not go further back than the letter n in the word configuration.
This behavior is only with some font types, like myriad or ubuntu.
Since i have no clue how to upload attachments to this forum i created a Box link
https://www.box.com/s/0boj6u2kgmwojbg9ubhd
In here i have a video of the behavior and a test project.

Answer 1

Not sure if this will help you, but in order to get my embedded fonts to render, I had to do:
                GlobalSettings.resolveFontLookupFunction = null;
                //setup text item from xml
                var res:XML = XML(xml.htmlText.children()[0]);
                var tf:TextFlow = TextFlowUtil.importFromXML(res,WhiteSpaceCollapse.PRESERVE);
                tf.renderingMode = RenderingMode.CFF;
                tf.fontLookup = FontLookup.EMBEDDED_CFF;
                txt.textFlow = tf;
                txt.textFlow.whiteSpaceCollapse = WhiteSpaceCollapse.PRESERVE;
                txt.textFlow.invalidateAllFormats();
The important lines ar the first and last.
