A whitespace is automatically added if caret is at leftmost and I press a key, browser is Android Webview

Hello
I am using codemirror version 5.56.16
Inside Android webView I am running a HTML file with CodeMirror for syntax highlighting.
There is a bug,
when the caret is at leftmost of a new line, and I press a key (for example letter A), the letter I pressed is added to the textarea but then a whitespace is also automatically added at the line, and if I press a backspace when the caret is at leftmost of a new line, a whitespace is also automatically added and I cant erase the line.
This issue only happened inside Android webView, didn't happen inside chrome and other browsers.
I tried setting smartIndent to false but the issue wasn't resolved.
here is my initialization code:

editor = CodeMirror.fromTextArea(document.getElementById("code"), {
				  mode : language,
				  autoRefresh: true,
				  lineWrapping: true,
				  lineNumbers: true,
				  theme: theme
				});
