Reproduce:

• Navigate to Cockpit Process Dashboard
• Reload the Page
• Goto a process definition page
• On the process definition page, in the process instance list tab, enter a filter that returns at least one result
• click on Cancel instances

Expected:

• Process Instance Cancel page search query contains the process definition id and the filter query from the previous page
• Process Instance Cancel page lists only those instances that match the filter query

Observed:

• Process Instance Cancel page search query is empty
• Process Instance Cancel page lists all instance
• after performing the same procedure again (without a page reload), it works as expected
