Bug InputField on Android swallows up the first letter after clearing the inputfield

I'm running into the issue, that when I clear the content of an inputfield (e.g. after the user inserts a SPACE), the first letter afterwards will be swallowed if I type fast enough (<300ms). This can be easily reproduced by this code:

Code (CSharp):

1. public TMP_InputField inputField;
2.  
3. void Update()
4.     {
5.         if (inputField.text.Contains(" "))
6.         {
7.             inputField.text = "";
8.         }
9.     }

This only happens on Android, it works fine in the editor (might be an android architectural issue?)
