POM XML editor undo broken in Eclipse EE 2025-06.

[garretwilson]

In Eclipse EE 2025-06 on Windows 10, the "undo" feature of the POM editor is broken all over the place.

If I start with a file in version control, make changes, and then repeatedly hit Ctrl+Z to undo, I would expect to get back to the original file. But instead, I get missing characters, such as the last letter of an XML tag or the ending delimiter of a tag, such as this:

				<type>pom</type>
				<scope>import</scope>
			</dependency
		</dependencies>
	</dependencyManagement>

Note that </dependency is now missing its ending delimiter >.

So the XML editor is somehow corrupting the undo history.

The XML editor/formatter has never been right ever since the engine was swapped out a few years ago. See e.g. #1873 and many others.
