In VS Code, if I swap between multiple tabs quickly, the CodeLens for references disappears and re-loads every time, which is annoying and jarring.
Is there a way to increase the cache or persistence of CodeLens annotations so that, for example, all open tabs do not reload & reflow every time?
No, as of VS Code 1.13 code lens persistence is not something you can control.
