bug: resizing with the grid on goes smoothly, from the wrong side

[ES-Alexander]

Bug description

Resizing widgets from the top or left side when the grid is turned on results in the resizing happening from the other side and then jumping once a new grid size is reached:

Screen.Recording.2025-01-07.at.12.52.59.am.mov

Steps to reproduce

1. Open Edit Mode
2. Enable the grid
3. Resize a widget from the right or bottom side
4. Works fine
5. Resize it from the top or left side
6. 🥲

Primary pain point(s)

This isn't particularly problematic (functionally), but it feels really janky.

If the grid is enabled then I would expect resizing to just snap between grid options, like is done with movement.

That said, if we decide we want to support smooth resizing then it should at least be smooth from every side, and not have some of them from the opposite side to the one the mouse is actually holding onto.
