positionAt() function gives the wrong result if the line ends with an image and this line is wrapped by wrapMode

This function gives wrong result if line ends with an image and this line is wrapped by wrapMode.
 https://doc.qt.io/qt-5/qml-qtquick-textedit.html#positionAt-method

Steps to reproduce:
1. Create TextEdit component with rich text format.
2. Add text with an image at the end of the line, for example - "This line breaks by warp and ends with an image <img src='qrc:/images/arrow.png'>This line breaks by warp"
3. Set TextEdit width to be equal with line break after the image
4. Then the function positionAt will give an incorrect result, if X coord is outside of the line.
 
For example, if the text is 10 characters long plus 1 char is an image, total length will be 11. If there is no line break, then function gives the correct result 11, even if the x coordinate is out of line. It also works if the line breaks with line break character <br>.
But the problem occures when line breaks with wrap mechanism and positionAt will return 10 if the X coordinate is outside the line, but total length is 11.
 
I attach video and qml code, modified TextFieldPage.qml file from Gallery example.
Log:
qml: Mouse click coord 252.8 37.0 char pos 42
qml: Mouse click coord 259.1 37.7 char pos 43
qml: Mouse click coord 267.7 38.5 char pos 44
qml: Mouse click coord 286.5 38.7 char pos 45
qml: Mouse click coord 296.4 39.0 char pos 46
qml: Mouse click coord 306.8 38.2 char pos 46
qml: Mouse click coord 321.6 39.5 char pos 45
qml: Mouse click coord 326.4 39.8 char pos 45
qml: Mouse click coord 329.9 40.0 char pos 45
qml: Mouse click coord 334.8 40.0 char pos 45
 
You can see, that the X coordinate is increasing, like the result of the function, but when X exceeds the width, it gives an incorrect result, 45 instead of 46.
