Upgraded from Jenkins 2.60.1 to 2.150.1, and now have a problem with PerfPublisher display, where it is showing html-text on the web-page.

For example, in the build page, next to the graph icon for the publisher is the literal text <div class="progress-container">...

PerfPub 8.05 was installed before the upgrade, and has no pending upgrade.

The "Matrix build test report" (from left-hand icon bar) page shows (literal) <table class="matrix_table">...</table>
