create an ordinary gwt project, version 2.8.0-rc3 and 2.8.2, and the timer in demo makes rpc polling requests. Memory continues to grow in ie11. The timer stops memory from being freed. Growth knows that the browser is stuck.

(the requested data indicates that random numbers such as timestamps must be included in the data, that is, to ensure that the data in response to each request is not completely consistent, otherwise the memory will not continue to grow)

in other browsers such as chrome, memory increases, but is relatively stable.

is there any solution? it"s a headache.
