    Hello, so I'm getting error from TMP text input in Unity 2021.3.4f1, TMP version 3.0.6:

    IndexOutOfRangeException: Index was outside the bounds of the array.
    TMPro.TMP_InputField.GenerateHightlight (UnityEngine.UI.VertexHelper vbo, UnityEngine.Vector2 roundingOffset) (at Library/PackageCache/com.unity.textmeshpro@3.0.6/Scripts/Runtime/TMP_InputField.cs:3741)
    TMPro.TMP_InputField.OnFillVBO (UnityEngine.Mesh vbo) (at Library/PackageCache/com.unity.textmeshpro@3.0.6/Scripts/Runtime/TMP_InputField.cs:3568)
    TMPro.TMP_InputField.UpdateGeometry () (at Library/PackageCache/com.unity.textmeshpro@3.0.6/Scripts/Runtime/TMP_InputField.cs:3504)
    TMPro.TMP_InputField.Rebuild (UnityEngine.UI.CanvasUpdate update) (at Library/PackageCache/com.unity.textmeshpro@3.0.6/Scripts/Runtime/TMP_InputField.cs:3479)
    UnityEngine.UI.CanvasUpdateRegistry.PerformUpdate () (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/UI/Core/CanvasUpdateRegistry.cs:215)

    I checked it in debugger and m_CaretSelectPosition from line 3741 is equal to 0 so when trying to get element of index [m_CaretSelectPosition - 1] it's getting outside the bounds. Is there any solution to fix it?

    EDIT: It seems like I managed to fix this problem by myself. It seems like this bug was coming from another bug in my code that was creating input field outside of canvas.
