FreeRDP: ERRINFO_INVALID_INPUT_PDU_MOUSE and exit on middle mouse button click

Describe the bug

When connected to any client, if I use the middle mouse button, the program forcibly disconnects from the remote host.

[10:43:01:915] [8258:8259] [INFO][com.freerdp.core] - ERRINFO_INVALID_INPUT_PDU_MOUSE (0x000010D0):(a) A Slow-Path Mouse Event (section 2.2.8.1.1.3.1.1.3) or Extended Mouse Event (section 2.2.8.1.1.3.1.1.4) has been received with an invalid pointerFlags field.
(b) A Fast-Path Mouse Event (section 2.2.8.1.2.2.3) or Fast-Path Extended Mouse Event (section 2.2.8.1.2.2.4) has been received with an invalid pointerFlags field.

[10:43:01:917] [8258:8259] [ERROR][com.freerdp.core] - freerdp_check_fds() failed - 0
[10:43:01:917] [8258:8259] [ERROR][com.freerdp.client.x11] - Failed to check FreeRDP file descriptor

I can live without it, but it would be nice to have a work-around that doesn’t close the connection.

To Reproduce Steps to reproduce the behavior:

1. open a connection from linux to a local windows VM.
2. click the middle mouse button

Expected behavior Either nothing should happen, or the middle mouse button should be passed through to the remote host.
