[BUG]: scattergl hover freezes with more than 100.000 points all with different x but same y

Description

In scattergl, when you have more than 100.000 points the scattergl freezes when trying to hover, more informations in the steps to reproduce.

Steps to reproduce

In version 4.0.0
Create a scattergl with 100.000 points with x just the index of the point and y all the same.
you can use this snipper

const n = 100000;

Plotly.newPlot('graph', [{
  type: 'scattergl',
  mode: 'markers',
  x0: 0,
  dx: 1,
  y: Array(n).fill(0)
}]);

The default hovermode will be ok, no need to change it.
Try hovering on the point: the app freezes immediately.
Staying in the horizontal line of the points will make it look a little slow but normal, but when you exit from the line it freezes again.
Try removing one point (99.999 points): the freeze is gone.

Notes

Probably related to #6792 and #5790 but can't confirm if it's completely the same, this is more specific.
It is probably due to to the collapsation of the algorithm that comes in in a scattergl when there are TOO_MANY_POINTS (exactly 100.000).

首先使用 Plotly.js 4.0.0 中提供的 scattergl JavaScript 代码片段重现该问题，比较 100,000 个点和 99,999 个点时的悬停行为。跟踪 scattergl 的悬停路径以及报告中提到的 TOO_MANY_POINTS 处理逻辑，并参考 issues #6792 和 #5790。对于报告中的数据，悬停不再冻结或变得异常缓慢，即表示完成。
