VSCode color problem when use single quote with object value

After the recent VS Code updates, I noticed that the colors of my code have changed.

When I use the following code, everything works fine:

:class="{
  focused: isAddingStatus,
}"

However, when I add conditions with single quote like this:

:class="{
  'no-result': !dataList?.length,
  focused: isAddingStatus,
}"

code colors are corrupted.

How can I fix this issue?
