Brief summary of the bug. What is it ? Where is it ?

When enabling precision on a heatmap report with persisted tooltip, the tooltips are duplicated on the heatmap.

Steps to reproduce:

• Create a heatmap report
• Open the configuration option popover and enable "Tooltips - Show absolute values"
• Enable the "custom precision" option inside the config

Actual result:

• The tooltips with does not have custom precision is still displayed, which results in two tooltips on top of each other.

Expected result:

• The tooltips with no precision are replaces with the precision tooltips so that we only have one precision at a time.

Testing Notes:

• Create a heatmap report
• Open the configuration option popover and enable "Tooltips - Show absolute values"
• Switch the "custom precision" option inside the config on and off
• Switch "Show Relative Value based on process instance count" config on and off when "Show Absolute Value" is enabled
