描述

G lets you enable grab and then hit X or Y once for a global axis (document space) and a second time for a local axis (layer space), but the dashed line visualization is drawn incorrectly in the latter case:

When transforming in local space, it should tilt the dashed line with the local space as well, and draw just the X or Y component instead of both.

See this comment for a little more detail.

研究方向
Read the referenced comment (issue #3527 comment) for additional context on expected behavior. The bug is in the dashed line visualization during grab with local axis constraint. Currently it draws both X and Y components; it should draw only the constrained axis tilted with the layer's local space. Search for the drawing code for the dashed line (likely in the viewport rendering module) and the logic that determines whether the axis is local or global.
