Hi everyone,  
In the last few weeks, I have found that the `@profview` macro from the [VSCode extension](https://www.julia-vscode.org/docs/stable/userguide/profiler/) shows a blank tab the first time I run it, and then gives me the flame graph on the second run. Does it happen to anyone else?

Yeah, I’ve experienced the same. The weird thing is: after the second flame graph is rendered, if I go back to the initial flame graph’s tab, I see that it, too, is now rendered.
