Data Table header disappears #574

Open tippytappy opened 1 year ago

tippytappy commented 1 year ago

Describe the bug

When using the 'local_data' data table the headers sometimes disappear when moving the cursor between the header and the rows. I can't find a more precise combination, it seems random.

To Reproduce Steps to reproduce the behavior:

  1. Go to this workbook: https://observablehq.com/d/d65648172da5ead6
  2. In the 'local_data' cell move the cursor between the header and table rows, and from column to column.

Expected behavior The user can move the cursor over any part of the data table in any way without the header disappearing.

I suspect that this is a hardware acceleration bug caused by repeated instantiation and removal of SVG elements rerendering.

Are you able to reproduce this problem on other devices?
