Below are the files that still use lodash-es because es-toolkit doesn't yet have support for extend and cloneDeepWith:

• extend in engine/src/view/observer/domeventdata.ts
• extend in ui/src/model.ts
• cloneDeepWith in ui/src/template.ts
• cloneDeepWith in utils/src/config.ts
• cloneDeepWith in watchdog/src/editorwatchdog.ts

TBH, this is the first time I heard we keep lodash... I thought it's 1:1 replacement, and having two libs makes less sense for me.

R- from me, as it's increasing dependencies count w/o discussing this openly. And what are potential workarounds for this.

We've decided to put this on hold until extend and cloneDeepWith are available in es-toolkit.

I'll also contribute to the isElement implementation because it cannot be replaced with simple instanceof HTMLElement in our case (as I did in the PR).
