What is the reason for browser-sync slowdowns when using WebStorm?

Question

webstorm

The first changes are transferred to the browser instantly, after 20-30 changes reloading the page or injecting styles starts to noticeably slow down, after 50, incredible brakes begin, which can only be solved by reloading the task. What can be wrong?
The problem is not in tracking changes, and not in the speed of other tasks, they work out instantly after the changes. The delay is only in transmitting the changes to the browser. The problem is observed only in WebStorm, in the same Atom and VS Code there is no problem, everything flies on the same config.
Can anyone come across? I really don’t want to change from my favorite IDE, but it’s completely impossible to work with
PS Win 10, everything else is the latest stable versions, but the problem has been observed for a long time, and on earlier ones.
PS 2. You don't need to ask for configs, the problem is relevant even on a minimal example from the browser-sync site.
