[BUG] Issues with Maps and Table visualizations in pdf/png reports

[liamhess]

Describe the bug
The reports that opensearch dashboards produce have multiple issues.
One is that table fields just get cut off. This is happening since version 2.5 in which, as far as I understand, Opensearch changed the underlying engine that produces the reports from headless chromium to html2canvas?
Anyway this is how tables look:

Also, maps don't get displayed at all:

Then also if a dashboard is too large it just gets cut off. This obviously shouldn't happen but is a minor problem since

Most dashboards will never be that big
If you run into that issue, you can always split it into half and do two reports
However the table bug is really weird and if fixing is not viable maybe going back to headless chromium would be an idea.

To Reproduce
Steps to reproduce the behavior:

Go to the https://playground.opensearch.org/
Go to any dashboard that has tables or maps (for the table issue: visual consistency dashboard, for the maps issue: global flight dashboard)
generate a pdf report of either of the two
look at it and see that either the tables or the maps are broken
Expected behavior
The reports shouldn't have those issues, they should be as close to what you would see on the website.
