Description

Hi, this is a reproducible bug that we have run into in our charts. Unfortunately, this only happens on Chrome browsers which the majority of our users are using.

When using a dynamic zoom level control for scaling, there is unexplainable sizing issues with the annotations on the plot. For whatever reason, this occurs after clicking on the chart.

I have attached a minimal reproducible example with steps:

I am not sure why this occurs when the content-editable element is present.

Here is a video of what happens:

And some screenshots:

Perhaps someone could shed some light on this or has a workaround that we could use.

Research direction

Start by reproducing the issue from the linked CodePen in Chrome, following the dynamic zoom, chart click, CSS transform, and content-editable interactions. Trace how the chart updates annotation sizing after the click and compare behavior with and without the content-editable element. Done means annotations retain the expected size after clicking the plot.
