[Bug] Trailing Semicolon Is Removed on Autocomplete Insert

[kaji2]

In version 2.8.3, inserting a CSS variable via autocomplete removes an existing trailing semicolon.
This issue does not occur in version 2.8.2.

Environment

• VSCode: 1.107.1
• OS: Windows 11 (25H2)

Steps to Reproduce

1. Prepare the following CSS code, where | indicates the cursor position:

.foo {
 color: |;
}

2. Trigger autocomplete and insert --color.

Expected Behavior (v2.8.2)

The semicolon at the end of the line should be preserved:

.foo {
  color: var(--color);
}

Actual Behavior (v2.8.3)

The semicolon is removed after insertion:

.foo {
  color: var(--color)
}
