Hi,
I often use the display mode property of a textbox to allow/disallow editability of a textfield. This has worked without issue in the past however I recently check my app to find that all my text inputs were filled with "X" marks where I have set the display mode to disable. I have shown an example below:

The x marks do not appear in the online developmetn enviroment but appears in the web browser when the app si deployed. I have run a basic test to show this. I can also note that the X does not appear when runnig the app on ios or IE but occurs in chrome.

Is this a new "Feature"? if so how can i remove it so users can actually view the content of the textinput?
