Highlight issue in v4.30 and 4.31

[PavelJANDA]

Hi,

Found an issue with FeatureLayerView.highlight in version 4.30.

When you use highlighting on a polygon feature layer, CPU spikes to about 15% (depending on how powerful your machine is) and it will stay that way forever even when no map interaction is happening. In addition to that, GPU activity is also high.

We also noticed that if browser session is left open for about 10 mins (again might depend on how powerful your machine is) and then refresh the page, you will get Array buffer allocation error from mapViewDeps.js file. This is how we found this issue originally.

We originally identified this issue in 4.30 but it seems to start happening in 4.29. It is present in 4.30, 4.31 and also in version 4.32 (next).

Thanks for any insights,

Pavel
