Iframes doesn't load to completion when in tab with forceRender

• I have searched the issues of this repository and believe that this is not a duplicate.

Steps to reproduce

Let the first visible chart load fully. Then after a couple seconds, switch to another tab.
You can see that the loader is gone but the chart haven't finished to load.

What is expected?

We expect that the charts (that are embeded in frames) loads fully, even without focus

What is actually happening?

When we switch tabs, the iframes stop loading while in background.

We are using rc-tabs through antdesign, but I managed to reproduce the bug with rc-tabs, so I'm reporting it here also.
Note we did not had this bug with antdesign 3, it appeared in ant 4.

Apparently, it seems to be working with rc-tabs 10, but it may need to be double checked on your side (did not managed to fully integrate rc-tabs 10 in my codesandbox).

Start with the CodeSandbox reproduction in index.js and inspect how rc-tabs 11.7.0 handles forceRender when switching tabs. Compare the behavior with rc-tabs 10 as suggested in the report, then verify in Chrome on macOS or Linux that an embedded chart continues loading to completion while its tab is unfocused.
