Describe the bug
Unlike move, which (in plugins/common/wayfire/plugins/common/move-snap-helper.hpp) uses view->tile_request(0), resize does view->set_tiled(0).

tile_request emits the view-tile-request signal which is handled by grid. So by not using it, resize doesn't let grid know the latest information. As a result, when untiling a view via right-click resize, the next grid snapping of the view won't work correctly, there will be a weird offset to the positioning!

Sadly the easy fix (just changing which function resize calls) has a side effect: a weird snap at the beginning of an untiling resize — I guess we also need the adjust_around_grab part of the move-snap-helper.

To Reproduce
Steps to reproduce the behavior:

1. Snap a window to the top
2. Resize (via button binding) to unmaximize
3. Try to snap again, observe weird offset
