Issue Summary

The source code editor in Confluence no longer supports regular expression (RegEx) searches. When the "RegEx" checkbox is checked, the search behaves like a normal text search instead of a RegEx search.

Steps to Reproduce

1. Open a page in Confluence and switch to the source code editor.

1. Check the "RegEx" checkbox in the search panel.

1. Enter the RegEx pattern </?p> in the search box.

1. Observe the search results.

Expected Results

The search should find all instances of <p> and </p> tags, as these match the RegEx pattern </?p>.

Actual Results

The search does not find any matches. It behaves like a normal text search, which does not interpret the input as a RegEx pattern.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
