Describe the bug
When more than 50 connection points are created to align with the 10pt grid spacing, the spacing between the connection points becomes irregular.
To Reproduce

1. Correct behavior
When using the Alt+Shift+Q shortcut to create 50 connection points aligned with the grid spacing on a rectangle with a height of 510, and then closing the window and checking the connection points again using the Alt+Shift+Q shortcut, the connection points are created on the grid as intended.

Reopen: Alt +shift+Q

2. Bug behavior

Using the Alt+Shift+Q shortcut to create 51 connection points aligned with the grid spacing on a rectangle with a height of 520, and then closing the window and checking the connection points again using the Alt+Shift+Q shortcut, it can be observed that the connection points are not positioned on the grid. This irregular creation of connection points becomes more pronounced as the number of connection points increases.

Reopen: Alt +shift+Q

Expected behavior
Even for shapes larger than 510pt in size, connection points are accurately created to align with the 10pt grid spacing.
