Tested this DP. All the other features are working as expected.

1. Checked for other users if changes are reflected.
2. Checking widget d&d on all canvas size. > Widgets in 'Dekstop' size appears zoomed out (Fonts, widgets appear smaller) when compared to the rest of the canvas size
3. Widget shadow tail is seen when widgets are moved on canvas
4. UI on datasource and query pages have misalignments
5. Since these icons are not clickable, its confusing for users
6. When the first pane size is increased, the canvas is lost completely. https://loom.com/share/4033fe60e3054a189bb8f5282c6aee88
