Issue with spaces when using a iPad scriber

The client has reported the following issue:

"For the past few weeks, I have been experiencing a problem with the platform – when entering text using a iPad scriber, spaces are not inserted automatically.

Please see the example in the attached screenshot. This does not appear to be a hardware or software update issue, as spaces are inserted automatically in every other application.

The same problem occurs in both Safari and Chrome, on both an iPad and a Windows laptop.

Would it be possible to investigate and fix this issue?"

Could I please count on your help with this issue?
