Suspected memory leak #319
Description
Bug Description:
While working on the pixi.js-legacy upgrade (#317 ), I noticed Jest reporting a potential memory leak:
I investigated using the theia-trace-extension example application, producing heap snapshots, and noticed that opening and closing trace views / trace experiments, results in an evrer-growing heap usage (even after manually triggering garbage collection).
See below for a screen capture - a "diff" between two heap snapshots, between which I opened and closes several trace views. The "detached" DOM objects seem to be related to timeline chart / pixi (e.g. WebGL canvas):
