Have errors in utils.js && ReactGridLayout.js about react-grid-layout HOT 3 OPEN

using 1.4.3

from react-grid-layout.

is this observed when the JS out compile module to be commonJS in babel or webpack config ?

We're hitting this too. The problem is the optional chaining operator (i.e., ?'s) usage in the JS output. Line 360 in ReactGridLayout.js, for example looks like this in 1.4.3:

      !((_e$nativeEvent$target = e.nativeEvent.target) !== null && _e$nativeEvent$target !== void 0 && _e$nativeEvent$target.classList.contains(layoutClassName))) {

and this in 1.4.4:

      !e.nativeEvent.target?.classList.contains(layoutClassName)) {

The former looks like babel output handling an optional in vanilla JS whereas the latter is leaving the optional chaining in. If you're targeting pre-ES2020 (or using an older browser) it will barf on this.

Perhaps this was from the node version switch from 16 -> 18? That looks like the biggest change in the diff: 1.4.3...1.4.4.

Maybe this shouldn't be a patch release?
