there is a good news for this issue, but need end user's verification.
in recent 2 weeks, we got a similar report which only have issue on chrome.
in the end, we're able to reproduce this issue on user's website and have a fix for it quickly. the most time is spent on reproducing the issue.
please force re-install the latest 4.2.4. should fix the issue.
and thanks for the discussion in this thread. so when the user reported us the issue, I immediately realized that it maybe the same issue discussed in this thread for a long time but no result yet.
