After upgrading to 2026.8 a screen fails to render its grids after return. It is not consistent behaviour, but it is quite common. I’m observing this in Microsoft Edge.
Resizing the browser window causes to render the grids.
Browser console contains following error messages that appear when I switch to the other tab:
index-D97KywrS.js:592 Focus was requested on an invisible table. This should not happen.
