The locust chart shows that data is still being recorded after the timed run time expires

Description

When I started locust, I set a scheduled operation task for 2.5 hours. After the completion of the task, the report shows that the task is executed in 2024/9/23 22:01:07 to 2024/9/24 00:31:07. However, when I check the report on the web interface at 2024/9/24 08:09:00, Found that the timeline of the chart goes straight to 2024/9/24 08:09:00

I use the following command

Command line

locust -f ./locust_run.py --master --master-bind-port=8682 --web-port=8677

Same issue.

I commented out a line to fix this:
locust version: 2.31.8
./locust/html.py
line 55:

    failures_statistics = sort_stats(stats.errors)
    exceptions_statistics = [
        {**exc, "nodes": ", ".join(exc["nodes"])} for exc in environment.runner.exceptions.values()
    ]

    #update_stats_history(environment.runner, end_ts)    #this line
    history = stats.history

    is_distributed = isinstance(environment.runner, MasterRunner)
    user_spawned = (
        environment.runner.reported_user_classes_count if is_distributed else environment.runner.user_classes_count
    )

I think this is a way to update the results as you perform the loadtest, but the loadtest is over when you get the report, so you should not update.
And then the report is normal and I'm not sure if it will cause any other problems, but I haven't found anything so far

Good,But this seems to raise new questions,After I refresh the Locust web interface,No data is displayed on the statistics screen

@andrewbaldwin44 and I are pretty busy at the moment. @PlanetartRoc 's fix looks promising (feel free to make a PR) and @zhenhuaplan second issue is also worth investigating.

This problem should not be related to the html.py.

When the loadtest stops, the list of data will be empty, suspected to be related to the front-end judgment of the loadtest of the test execution state
