Monaco Editor Playground Code

var editor = monaco.editor.create(document.getElementById("container"), {
	value: "// First line\nfunction hello() {\n\talert('Hello world!');\n}\n// Last line",
	language: "javascript",
});
setTimeout(function () {
	editor.getDomNode().classList.add('hidden');
	editor.setValue("function hello() {\n\talert('Hello world!');\n}\n");
}, 2000);
setTimeout(function () {
	editor.getDomNode().classList.remove('hidden');
	editor.render(true);
}, 4000);

Reproduction Steps

Run the code in the playground using Firefox or Safari.

After 2s it will hide the editor, change its content, and after another 2s it will show the editor again.

Actual (Problematic) Behavior

After the editor is shown again, it is left in a broken state, even despite the editor.render(true) call. It is impossible to place cursor or select text within a line using the mouse. Clicking on a line will always place the cursor at the end of the line.

Expected Behavior

The editor is expected to function normally in this case.

Additional Context

The issue cannot be reproduced using Chrome.

Start with the linked Monaco Editor Playground reproduction and compare behavior in Firefox or Safari after the editor is hidden, updated with setValue, shown, and refreshed with render(true). Trace the editor's mouse positioning and rendering behavior across that sequence; done means the restored editor allows the cursor and text selection to work normally, while Chrome behavior remains unaffected.
