copy location problem

I set up auto copy selected characters, and right click auto paste, so I double click abc, and then right click

original：
abc [Blank space] cursor

result:
abc cursor [Blank space]

i expected result:
abc [Blank space] abc cursor

It seems that when I double-click to select a character, the cursor goes to the front of the character，Is there somewhere I can set it up？

Reproduce the double-click selection followed by right-click auto-paste with the reported auto-copy and auto-paste settings, comparing the cursor and inserted text. The issue names no source file or test; done means determining whether a setting or fix makes the pasted text appear after the blank space as expected.
