Broken syntax highlighting in typescript after type followed by `label:`

[mbnuqw]

Type: Bug

1. Open vscode 1.77.1 or above (the issue was found on 1.77.1 and reproduced on 1.77.3 and insiders build)

2. Open .ts file:

   function example() {
   // Without label: OK
   let a = 0
   let A: number | undefined
   while (a < 100) {
   const r = Math.random()
   if (r > 0.9) {
     if (r > 0.95) A = 123
     else A = 321
     break
   }
   a++
   }
   
   // With space (or ';'): OK
   let b = 0
   let B: number | undefined
   
   loop1: while (b < 100) {
   const r = Math.random()
   if (r > 0.9) {
     if (r > 0.95) B = 123
     else B = 321
     break loop1
   }
   b++
   }
   
   // Not OK
   let c = 0
   let C: number | undefined
   loop2: while (c < 100) {
   const r = Math.random()
   if (r > 0.9) {
     if (r > 0.95) C = 123
     else C = 321
     break loop2
   }
   b++
   }
   
   let one = 1
   let two = 2
   }

3. If ts type followed by 'label:' syntax highlighting of the next code is inconsistent
