When I enable accessibility in the Angular Report Viewer, based on the HTML5 Report Viewer, I get the following console error:
Uncaught TypeError: Cannot read properties of undefined (reading '_controller')
at telerikReportViewer:1:15863
at Ce. (telerikReportViewer:1:16167)
at Ce.n (telerikReportViewer:1:26372)
at Ce.trigger (telerikReportViewer:1:26686)
at ce (telerikReportViewer:1:32782)
at Object.updateUI (telerikReportViewer:1:43789)
at telerikReportViewer:1:93236
The report viewer continues being functional despite the error but accessibility text is missing for page number, export, and buttons(incl. parameters area).
