Reproducible steps:

1. Open ZSS Application
2. Create a multi-row merged cell
3. Create a hyperlink within this cell
4. Mouse over this hyperlink

Expected result:

The mouse cursor should change to a hand, indicating the hyperlink is clickable.

Actual result:

The mouse cursor is still an arrow. The hyperlink can only be clicked once the merged cell is focused.

If the sheet is protected, and cell selection is not allowed, then the hyperlink can never be clicked.
