dash如何更新Figure的同时保持缩放和视角

我觉得他不能这样是一个bug,
即使

State(“graph”, “figure”),

直接把figure传后台, 数据里的layout就是错的
所以做了一个妥协的方案. 想要调整视角和缩放.就去手动按按钮停止刷新. 调整好了你再去点按钮继续刷新.
属于是脱了裤子放屁, 但他就是有bug,没办法
以下是这个方案完整的代码. 对我来说已经完整解决问题了

import dash
from dash import dcc, html, Input, Output, State
import plotly.graph_objects as go
import numpy as np

# 初始化Dash应用
app = dash.Dash(__name__)

# 全局变量（示例用，生产环境推荐用dcc.Store）
saved_camera = {}  # 存储用户调整的视角配置
n_frames = 100  # 动画总帧数（循环播放）
x = np.linspace(0, 10, 50)  # 固定X轴数据

fresh_ms = 100  # 多久刷新一次 单位ms
fresh_ms_stop = 99999  # TODO: 认为停止刷新是99999ms刷新一次
fresh_ms_go = 100       # 认为继续刷新是100ms刷新一次

stop_fresh = 0  # 初始是动起来

app.layout = html.Div([
    # 调试区域：显示relayoutData和当前视角
    html.Div(
        id="debug-panel",
