[Bug] Inconsistent selection behavior

Version

1.20.3

Link to Minimal Reproduction

No

Steps to Reproduce

1. disableSelectOnContextMenu: true
   Assuming you currently have a selected cell and right-click on it, the selection will not disappear

2. disableHeaderSelect: true、disableSelect: true
   Assuming a cell is selected and a certain range cannot be selected, clicking on that range will cause the previously selected cell to disappear;

Current Behavior

The selection effect of disabling Header Select and disabling Select should be consistent with disabling Select On Context Menu. Previously, there were selected cells, but clicking on 'Do Not Clear Selected Cells' should not clear them

Expected Behavior

When a column A has disabled HeaderSelect and disabled Selec properties set, first click on another column B cell to select it, and then right-click on column A cell to click, hoping that the previously selected cell still exists

Environment

- OS:
- Browser:
- Framework:

Any additional comments?

No response

Reproduce the behavior in VTable 1.20.3 using disableSelectOnContextMenu, disableHeaderSelect, and disableSelect as described in the issue. Trace the table's selection handling from those settings and verify that clicking or right-clicking a disabled cell preserves the previously selected cell consistently.
