Fix for espressif#3460 issue (#4424)

Browse Source 
Fixes: #3460

This code has been run in production for 1 month and it looks stable, no data dropped and it definitely fixes the issue described. I think that this can be merged to avoid using custom package referencing in PlatformIO that has been used in quite a few projects for now.
