Tooltip and Popover arrow placement is incorrect when placement is not center

### Description

The tooltip and popover arrow is not properly positioned when using non-center placement options (e.g., top-start, top-end, bottom-start, etc.). The arrow appears to remain in the center position regardless of the specified placement.

### Steps to Reproduce

- Create a tooltip or popover with placement set to top-start
- Add content that makes the tooltip or popover wider than the trigger element
- Observe that the arrow remains centered instead of aligning with the start position

### Expected Behavior

The arrow should be positioned to align appropriately with the specified placement

### Actual Behavior
The arrow remains centered regardless of the placement setting, creating a visual disconnect between the tooltip or popover and its trigger element.
