Select previous token when remove all inserted letters

[Pcosmin]

I create an token and then i insert one letter. After that when i delete the letter the previous token is automatically selected, and after that when i want to insert some tex, the selected previous token is replaced with the text. How can i avoid to automatically selecting previous token when delete all input text?

I am also seeing this issue. It would be interesting to optionally disable this.
