That's really interesting. I wonder if this is a Chromium-only issue? It may be worth filing a bug: https://bugs.chromium.org

I'm not an expert in this space, but it seems to me that the JavaScript engine could eventually clean up that memory, maybe based on some heuristics (e.g. the size of the original string, whether any references to the original string exist, etc.).

Same issue in Java at least for older JDKs. We used to have special (SAP) internal commands to detect this issue in the Eclipse Memory Analyzer.
