Huge CPU load on server side - probably when using "modify"

[ildar170975]

I have a test page with ~5..7 cards.
Every card shows a flex-table-card with ~5 rows.
Every card represents some example of using modify option.
Nothing super complex, just like this:

• math operation like "x * 100";
• string operation like split to substrings;
• convert a timestamp into Datetime.

Every time I open this page I observe a huge CPU load on a server side.
If an average CPU load (measured by top command) is 5..20%, now I see it about 95%.
I have to reboot the host then.

Using Chrome, Win10x64 as a client.
Using x86 mini PC as a server (Debian).
HA in Container.

this might also be solved by #103
