Summary

Fixes #13506

Occurred changes and/or fixed issues

• update wrongly used patterns for computed properties using $refs

Technical notes summary

• Just learned that $refs aren't reactive and in the first evaluation of a computed they are always undefined, which in conjunction with the condition this.isCodeMirrorContainerFocused && (ev.code === 'Enter' || ev.code === 'Space') triggered the focus (this.isCodeMirrorContainerFocused => this.currFocusedElem === this.$refs?.codeMirrorContainer => undefined === undefined).

Areas or cases that should be tested

• Import YAML modal (triggered from header)
• configmap, as per original issue
• ContainerShell -> opening terminal and clicking space

Areas which could experience regressions
