Research direction

Start by tracing the replaceRegex Maven configuration shown in the issue and how the replacement element is read and formatted. Reproduce the example with a leading space before {}; done means the replacement preserves that leading whitespace without breaking the formatter.

Description

I'm doing some replaceRegex rules and I'm attempting to replace some text with { } however the leading whitespace gets trimmed and doesn't get added.

I've tried numerous work arounds using unicode, cdata, escape codes, and they all get trimmed (or the formatter just breaks)

How the heck do i add a leading space in the replacement text?

 <replaceRegex>
    <name>collapseEmptyBlocks</name>
    <searchRegex>(?s)[\s\r\n]*\{[\s\r\n]*\}</searchRegex>
    <replacement> {}</replacement> <!-- why spotless remove the leading whitespace???  -->
</replaceRegex>
