Multiline does not resize rows with splitAt function

I am using the splitAt function with .enableMultiline(true) but the SplitAt columns are not resized to match.

Is this a bug ?

Unfortunately the problem cannot be reproduced locally.
The following sample works well:

If the problem still occurs for you please, provide with a demo link or a complete demo, where the problem can be reconstructed.
