Can't Match

I'm using the latest version github.com/mxschmitt/playwright-go v0.1100.0 // indirect

HTML code: For options with space:

<select name="cars" id="test1">
  <option value="t1">t1</option>
  <option value="t2">t 2</option>
  <option value="t3">t&nbsp;3</option>
  <option value="t4">t4</option>
</select>

Playwrite-go code:

// success
v,err:=page.SelectOption("#test1",playwright.SelectOptionValues{Labels: playwright.StringSlice("t 2")})
fmt.Println(v,err)

// failed
v,err=page.SelectOption("#test1",playwright.SelectOptionValues{Labels: playwright.StringSlice("t 3")})
fmt.Println(v,err)

Result:
