描述

I have the case where I initialize and destroy an SVG Element based on its visibility and experienced, that the wrapping g with its transform="matrix(...);" attribute is not reset after destroying it. When then re-initializing the object, it will show the SVG at a veeery small scale as a starting point. Because the translation is then applied on top of the already existing matrix.

I tried to just remove the transform attribute by hand but that didn't produce my wanted result.

Any suggestions?

研究方向
Investigate the destroy method implementation in the library (likely in the main source file, e.g., src/svg pan zoom.js). Look at how the transform attribute is handled on the SVG element or its wrapper group during initialization and destruction. Check comments in the issue for any reproduction steps or suggested fixes. Consider testing with a simple HTML page that toggles the SVG element's visibility to reproduce the scaling issue.
