Blazor active circuit metric lost track of an active circuit #63810
Description
I somehow got into a state where Blazor's runtime metric says I have no active circuits, even though I still have a working Counter page:
Here's my Counter.razor:
@page "/counter"
@rendermode InteractiveServer
<PageTitle>Counter</PageTitle>
<h1>Counter</h1>
<p role="status">Current count: @CurrentCount</p>
<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>
@code {
[PersistentState]
public int CurrentCount { get; set; }
private void IncrementCount()
{
CurrentCount++;
}
}I added a simple script in App.razor to pause and resume circuits based on visibility:
<!DOCTYPE html>

<script>
document.addEventListener('visibilitychange', () => {
if (document.hidden) {
Blazor.pauseCircuit();
} else {
Blazor.resumeCircuit();
}
});
</script>
</body>
