multiline TextInput text selection on android

[alexg93333]

On android the TextInput text selection is behaving strangely. On linux I can hold down the mouse and drag to select text, on android holding down touch and dragging doesn't have any effect at all, I noticed that if I try to select and drag a couple of times in a row suddently the whole text gets selected.

from kivy.app import App
from kivy.lang import Builder
KV = '''
BoxLayout:
    orientation: 'vertical'
    TextInput:    
        id: tinput
        background_color: "black"
        cursor_color: self.background_color
        foreground_color: 1, 1, 1, 1  # Set text color to white
        use_bubble : False
        readonly:True
        size_hint: 1, 1

        multiline:True

class MinimalTextInputApp(App):
    def build(self):
        return Builder.load_string(KV)
    
    def on_start(self):
        self.root.ids.tinput.text="""s ajlkk sajklsa jkl
            salajsa kljs alkjas
            as kjlsakjlasjlksakj
            a sjkasjlksalkja sa
            a sjaslkjksasj
            """
        return super().on_start()

if __name__ == '__main__':
    MinimalTextInputApp().run()

EDIT: I also noticed that on linux, after selecting text, you can click outside the text to clear the selection. On android it doesn't work. If I tap anywhere on the screen, even outside the element, the selection seems to be permanent.

EDIT 2 : I found out that the bug is due to readonly: True. If readonly is false, android text selection starts to behave correctly as on linux. On linux with readonly false or true the text selection behavior is correct in both cases. This is definitely a bug for kivy on android.
