Openhab Rules settings mains pages freeze in last 4.2.0 M3 when having a lot of rules.

Openhab Rules settings mains pages freeze in last 4.2.0 when having a lot of rules.

I notice that the rule settings main page (the one where you have all your rule listed), is freezing when you have a lot of rules defined. This happens in Chrome as well has in Firefox. The CPU seems to go up, and after a few seconds, the page display, but you can no more interact with it. My number of rules is about 62, and the problems seems to begin if you have about more than 40 rules.

I'm not able to said if it a new bug, or if it was occuring before as I add several rules in my setup last week, so possibly was already there in previous version.

This issue seems difficult to trace has the tab just freeze, as well has the developper tools, and the only action possible is to close the tab.

Expected behavior

Rule page loading and being able to interact with the page to see details of the rules.

Steps to reproduce

Create many rules > 50.
Navigate to the settings > rules pages.
Navigator freeze after loading and displaying the page

I'm not able to said if it a new bug, or if it was occuring before as I add several rules in my setup last week, so possibly was already there in previous version.

BTW it is not a new "bug", there was no change in the related code parts. The "bug" ever existed since openHAB 3.0, but it only occurs when there are many rule status changes. The UI gets the rule status in real-time from the server through a SSE event stream and processes the received data, and this processing was too slow.
