Custom visual that uses Fetch more data API causes browser to crash on switching pages in the report

We wanted to take 1 Million rows of data from user into Power BI custom visual.
By default we can make the custom visual to take maximum to 30000 rows by configuring count in dataReductionAlgorithm in Capabilities.json.

 

We are using Fetch More Data API (https://learn.microsoft.com/en-us/power-bi/developer/visuals/fetch-more-data) to implement the changes in custom visual to take 1 Million rows of data.
Note: We are loading 20000 rows of data on each fetch.

We are able to load 1 Million rows of data into custom visual.

However, when I switch tabs multiple times (at least twice/thrice), Power BI online browser is crashing.

When i replicate these steps in Power BI Desktop, I observed that Power BI desktop got closed automatically.

 

Please let me know if any one has come across this scenario previously.  

 

Additionally, please let me know how this issue could be resolved.
