Greetings, we have analyzed your requirement and we would like to inform you that currently we don’t have support to disable the popup while editing text in image editor.
Since, we have provided the multiple support (rotate the text, customizing text size and its style) in text edit mode, we cannot handle to edit the text directly in text element.
For example, if we rotated the text or provided the large text (or large font) and try to edit text directly in text element, it will not give right user interaction experience while editing text.
So, we have considered these cases and framed control architecture to show popup to edit the text (displayed as normal text even text in rotate and large text cases) in image editor.
