Kibana version:
9.3.1

Describe the bug:

When the Truncated string field format is applied to a field containing XML or HTML-like content, all angle-bracket tags (e.g. <element>, <ns:element>) are stripped from the rendered output in Discover. Only the text content between tags is displayed.

This is a regression introduced in 9.3.1 by #251892, which was backported to the 9.3 branch via 60e4862.

The issue does not occur on 9.3.0.

Steps to reproduce:

1. Index document:

PUT test-xml-truncate/_doc/1
{
  "@timestamp": "2026-03-16T10:00:00Z",
  "payload": "<root><item><name>Hello World</name><value>12345</value></item></root>"
}

2. Create dataview
3. Modify field in dataview to truncate

Expected behavior:

Truncate the field, with previous versions.
