### Reproduction Steps

The ě character should appear after pressing the corresponding key.

### Actual behavior

But nothing happens

### Regression?

_No response_

### Known Workarounds

_No response_

### Does this problem also occur in the CEF Sample Application

No

### Other information

_No response_

Start by reproducing the missing ě character in a WPF text field on Windows 11 with CefSharp 149.0.40, then compare the result with the CEF Sample Application, where the issue does not occur. Trace the CefSharp/WPF keyboard and text-input path; the work is done when Czech ě can be entered normally and the regression is covered by a suitable verification.
