Bug chrome file upload

To upload in chrome I use the following methode ( I have run the code in firefox before but now I want it in chrome)

xclick on upload button
filename dialog opens
xtype filename
xtype enter

Normaly it should work… BUT!

filename have a first letter as Capital but when xtype it into the upload promp it type as lowercase. So chrome will give an error.

can you record video?

Sorry I cant… But It happens on a xubuntu and kubuntu system. Didnt test on windows yet.
I copy the filename from another page and xtype it to the upload window. I have used the echo command to see if it does copy the name with capital and it does copy correctly. But xtype type it in lowercase in the upload file window.
