Bar text performance regression from plotlyjs 1.58.4 to 2.1

[darintay]

Bar charts with text appear to be several times slower to render in plotlyjs 2.1 than they were in 1.58.4.

Simple example here:

1.58.4: https://jsbin.com/winiqazavu/edit?html,output
2.1.0: https://jsbin.com/fahedevopo/edit?html,output

The 1.58.4 version runs in a couple of seconds for me, where the 2.1.0 takes over a minute. I've tried on Chrome and Firefox.

If you remove the text, everything renders quickly on either version.

Hey, we found some performance issues too.

Here is an example with 100k datapoints. When we use the 2.2.0, the whole plot freezes and has a very bad performance. When we use the plotly-1.58.4.min.js, everything works fine.

This is related to #5624 and #5638.
Please try setting textposition to "none" in your bar trace.

@archmoj Can you please check the example above regarding the performance of the scallergl plot.

@archmoj Can you please check the example above regarding the performance of the scallergl plot.

Please open a separate issue for the scattergl case.
Thanks.

Ah, it was suddenly trying to render the text inside all the bars? Makes sense why that would take a while.

Confirmed that textposition none fixes issues here, thanks!
