Description

Hi there! Zoom on double click does not work in IE. Some times it works for first time, but next double click does not have result. I have used for example http://ariutta.github.io/svg-pan-zoom/demo/inline.html and IE 11.0.9600/18450

Research direction
Examine the double click zoom handler in svg pan zoom.js, particularly the logic for toggling zoom state. The issue mentions intermittent failure in IE11 after first zoom. Check for browser specific event handling issues (e.g., event propagation, dblclick vs. click). Consider setting up an IE11 VM to reproduce. Since the issue is from 2016 and has no linked PR, verify if the bug persists in the latest version. Look at the project's tests for zoom behavior.
