No Sized Pane Does Not Collapse

[PMcDonough11]

Bug report

If you have a collapsible Kendo UI Splitter with 2 Panes and horizontal orientation, and one of them has size, the other pane will not be collapsible.

Reproducible

1. Go to this Progress Kendo UI Dojo
2. Collapse Pane B

Current Behavior

First pane remains at a fixed width.

Expected/desired behavior

The Pane should completely collapse similar to the 2024.3.1015 version(Dojo).

Environment

• Kendo UI version: 2024.4.1112
• jQuery version: All Supported Versions
• Browser: all
