Memory leak in structured-clone-holder

I'm using Firefox 81 on Ubuntu 18.04.5 LTS When left unattended, Firefox (MainThread process exactly) continues to consume memory, and it returned to system only when I open about:memory or about:performance pages.

On about:memory / Measure I see that most memory is consumed by structured-clone-holder item 6.5Gb. WebContent process consumes stable amount (2..3Gb), because I have many open tabs, but this amount is not changed during the time.

Are there any methods to understand what is caused the structured-clone-holder to grow so big?
