[Annotations] Tooltip looks bad when visualizing long values with no spaces

[stratoula]

Describe the issue
When you create an annotation and display in the tooltip a long value with no spaces, the annotations tooltip is being displayed badly. We can also see a scrollbar which is useless since the popover cannot be focused

To Reproduce
Steps to reproduce the behavior:
These are the steps to replicate in kibana

1. Create a test index with a field with a long value (no spaces)

PUT my-tooltip-test/_doc
{
  "timestamp": "2024-01-02T14:09:19+00:00",
  "field": "value",
  "long_field": "test_test_test:12356733:1gergrere-gergergreger:gergergerger:/asdasd/meow/woofandmeow"
}

2. Create a dataview
3. Go to Lens
4. Create an XY bar chart
5. Add an annotation
6. Set up the tooltip as

7. Hover over the chart and check the tooltip

Expected behaviour
I don't expect scrollbars, I expect the value to be nicely wrapped

Version (please complete the following information):

• Browser: Chrome
• Elastic Charts: 61.2.0 (it is also in prior versions as a user can replicate in kibana 8.11)

I was wrong, the annotations tooltip is a custom one, the problem is in Lens elastic/kibana#174836
