The online web demo sample
gets updated only in volume and service pack release. So we suggest you to use
our stackblitz sample which gets updated every week.
Could you kindly use our
stackblitz sample and check whether the issue occurs randomly when you are
using in the latest version.
We tried to replicate in the
latest version by highlighting , underlining and strike through by Zooming In ,
Zooming Out and in print and download too, but we were unable to replicate the
issue.
Sample: https://stackblitz.com/edit/angular-pfwgv3?file=src%2Fapp.component.ts
Kindly use the above sample in
which we have provided the latest version 20.4.53 and get the issue resolved.
