Regarding the M136 AT bullet ejection

When using the M136 AT, if you perform the sequence of looking through the scope → firing → unlooking through the scope in quick succession, the bullet’s hitbox does not appear immediately after firing; instead, the hitbox appears only after the bullet has risen.
I have created a video demonstrating this behavior on the actual gameplay screen.
Regarding the version in which this occurs, I have confirmed that it can be reproduced starting with version 1.2.3.5.
If there are any other issues that need to be verified or information that need
