It seems I may have a workaround.
I tried to fully replace the tooltip with a templated string with some html
inside, like this:
```
options: {
[...],
tooltip: {
formatter: (params) => `
<div><i>${moment(params[0].axisValue).format('ddd YYYY-MM-DD
HH:mm')}</i></div>
<div class="mt-[10px]">
${params
.map(
(series) =>
`
<div class="flex gap-[5px] items-center mb-[5px]">
<svg width="20" height="20">
<circle cx="10" cy="10" r="5"
fill="${series.color}" />
</svg>
${series.seriesName}: <b>series.data</b></text>
</div>
`,
)
.join('\n')}
</div>`
}
```
and I found out my example now works with Google Chrome without crashing.
Without this workaround, with approx 1500-2000 items moving between the
items would lead to crash after seconds; now it seems I'm unable to make it
crash again.
That would mean that the issue is in the way the internat tooltip is
managed, maybe some kind of caching strategy?
Hope it helps!
