System configuration

NVDA installed/portable/running from source:

NVDA version:

2024.1.0.31547

Windows 11

Name and version of other software in use when reproducing the issue:

Latest version of Chrome and Edge have the behaviour
Firefox doesn't
An old version of Chromium doesn't show the behaviour either. This is version 102.0.5002.0

This is using the Telerik grid software. They say they can't reproduce the issue, which may be because of the version of Chrome they are using

Just to add. This happens for me 80% of the time on my work and home PC. It doesn't happen for Telerik at all

I can reproduce this only when reporting of tables is enabled in document formating settings.

This error appears on every column that cannot be read by NVDA, this seem to be the first two columns.
I am not sure but this might be a web authoring issue. However, I wonder why there is a difference when I disable reporting of tables? Then it works as expected and all 5 columns are reported.

cc: @jcsteh any suggestions?

[Adriani90]

I tested in Chrome 124 with NVDA 2024.1.
cc: @aleventhal this seems to be reproducible only in Chromium browsers.
