Unfortunately, the report contains a dead link. Might be good to track this down and, if still reproducible, fix it in #7410?

Still a bug which manifests in different ways in both Firefox and Chrome:

data:text/html,before<div role="grid" aria-readonly="true"><div tabindex="-1" role="presentation"><div role="row"><div role="gridcell">cell content</div></div></div></div>

Firefox incorrectly reports the row and column counts as reported here.

Chrome doesn't render the cell at all.

Bugs need to be filed with both browsers.

P4 because we don't seem to be getting reports of this particular usage in the wild. If we see a specific case of this, we can raise the priority for filing browser bugs.

In Firefox 66.0.3 and NVDA 2019.1.1 this issue is still reproducible. I see this issue at work very often in SAP net viewer applications.

Following error is written to the log when trying to navigate in the table cell with ctrl+alt+arrow keys:

ERROR - scriptHandler.executeScript (17:41:56.723):

In Chrome 74 it works as expected. The text "cell content" is rendered into a cell and you can navigate by ctrl+alt+arrow keys.

I get this behavior also in many share point applications which contain grids.

Still reproducible in Firefox 71. @jcsteh is this something you could report on Bugzilla? Unfortunately this issue is quite severe in corporate environments, epsecially in sharepoint based interfaces and the table navigation does not work.

This should be addressed in Firefox 75 (currently in beta). The simple test case in #927 (comment) now works as expected.

@Adriani90, could you test whether the problematic SAP net viewer and SharePoint applications you mentioned are fixed now? I understand you may not be able to run beta software in a corporate environment, so we might have to wait until Firefox 75 final.

I'm closing this, since the test case is fixed, but please do comment with your findings. We should open a new issue if there are further problems.
