Invisible letters with key combinations and git log

Problem Description

Since I use commands like git status --branch --short and ls very often, I'd like to add key combinations for them in my bashrc with bind -x. They seem to work at first and are comfortable for me, but when I use them in certain situations, the text which I write in the lxterminal window later is invisible, so I can no longer use the terminal tab because I want to see what I type. The problem does not happen if I type the commands and press Enter instead of pressing key combinations.

How to Reproduce

Put the following line into ~/.bashrc: bind -x '"\ea":"ls -la"'
Open a lxterminal window in a git repository folder
Press Alt+a. This should list the files in the folder because of the bind.
Type git log and press Enter.
Press q to exit the git history viewing.
Type something. The letters are now invisible / not shown but it is still possible to type and execute a command.
