Report builder not formatting properly in browser in powerbi.com anymore but exports OK to word

We use report builder reports quite a bit but as of a month or so ago, the reports are not rendering properly in the browser in powerbi.com anymore.  The issue occurs in Edge and Chrome.

The report renders fine when we test in Report Builder and when you export the rendered report from powerbi.com to word or PDF it looks fine. It's just when you view it in the browser in powerbi.com, the lines of text of the report are rendered on top of each other  on the web page so it is unreadable. We are on version 15.7.1813.16 of report builder

Does anyone else have this issue?

It doesn't seem to occur for report builder reports which are rendered inside power bi reports
