File Upload Element - Choose File Button

[Parisi]

We notice that the Choose File Button is displayed even after a file has been uploaded. I would think that this button should not be displayed once a file has been uploaded. The user would click Delete and then the Choose File button would reappear.

So we did a bit more testing on this and it seems that clicking on the Choose File button replaces the current file. Does the existing file that was previously uploaded get removed. This is sort of confusing.

Can we hid the Choose File button until someone Delete's the previous file.
