Issue: [Accessibility] Accessible View does not get dynamically updated in Jupyter Notebook cell output
Labels: feature-request,accessibility,notebook-output

Type: <b>Bug</b>

CC @meganrogge 

When screen reader users augment current Notebook cell output in Accessible View via alt+F2, dynamic content does not get updated in the buffer, such as downloading progress on pip/conda packages and any computational progressive print.
