termux-dialog text dismissed when accidentally touch outside dialog

termux-dialog text dismissed when touched outside the dialog
I use termux-dialog text -m in scripts to enter a lot of text, and everything is fine until writing I accidentally click over the keyboard, outside the dialog: the dialog is dismissed and all my edits are lost. And for my workflow and my clumsy fingers this bug it's blocking, and actually I can't use termux-dialog anymore.

Steps to reproduce

• open termux
• run termux-dialog text -m
• write a lot of text
• click accidentally outside the dialog

Expected behavior
Would be very nice if the dialog would not be dismissed, at least, if is not possibile, fill the exit data with the edited text, so I can show the dialog again without loosing the edits.

Also, touching outside the dialog should return another code so the script can be able to differentiate between this case and hitting CANCEL. Currently there's no difference between these two cases and you can't determine which has occurred..
