When entering deepEdit mode with a double-click or F2 when using navigation, the entire text is selected. I am used to the text not being selected and the cursor being at the end of the text in the input, like in excel with F2. With enableCellEditOnFocus: true and navigating the grid, it makes sense for the entire text to be selected, because when entering new text, the old text gets overwritten - behavior like excel. But when entering deepEdit with F2 - also like in Excel - you usually want to change the text and not overwrite it.
