In InDesign CC (Version 18.3), there is a persistent bug where a line jumps unexpectedly by half its stroke weight when attempting to change its length. This issue has been present for some time and occurs consistently. Enabling or disabling the scaling options in the settings does not have any effect on this behavior.

Steps to Reproduce:
1. Open InDesign CC (Version 18.3) on the affected system.
2. Create a new document page or open an existing document.
3. Draw a line with any length and stroke weight.
4. Select the line to edit it.
5. Try to change the length of the line by dragging one of its ends or adjusting the properties in the control panel.
6. Observe how the line unexpectedly jumps by half its stroke weight.

Expected Behavior:
The length of the line should adjust accordingly to the changes made without any unexpected shifts or jumps.

Actual Behavior:
When attempting to adjust the line's length, it consistently jumps by half its stroke weight, resulting in incorrect positioning.

Additional Information:
- The bug consistently occurs and affects every line when attempting to change its length.
- Enabling or disabling the scaling options in the settings does not impact the occurrence of this issue.
