textinput v2: Cursor changes color of text

**Describe the bug**

This cursor changes the color of the text around it & there is no way to control it.

**Setup**
Please complete the following information along with version numbers, if applicable.

- Terminal Emulator kitty
- Terminal Multiplexer N/A
- Locale en_US.UTF-8

**To Reproduce**
Steps to reproduce the behavior:
1. New textinput model
2. Set different color of text
3. Enable cursor (virtual or not)
4. Blur & focus both produce weird results

**Source Code**
n/a

**Expected behavior**
The text foreground color to remain consistent

Blurred:

**Additional context**

I believe #892 would fix it - I did a temporary fix for this on my local machine, but that PR is more comprehensive:

```
if pos < len(value) { //nolint:nestif
char := m.echoTransform(string(value[pos]))
// vvvvvv this
m.virtualCursor.TextStyle = styles.Text.Inline(true)
// ^^^^^^ this
m.virtualCursor.SetChar(char)
v += m.virtualCursor.View()
```
