height-sizing: Vertical scrollbar not showing when editor has less than 3 lines

[Marin Sokol]

Describe the bug

If you create an editor using the minLines/maxLines API, so something like

var editor = ace.edit("editor3");
editor.setOptions({
    maxLines: 2,
    value: "console.log('hello world')\n".repeat(10),
});

which I added to the resize demo: https://github.com/ajaxorg/ace/blob/master/demo/autoresize.html

the vertical scrollbar is not shown for less than 3 lines, see below:

Expected Behavior

I expect it to be shown as a user doesn't have a good indication right now that there is more content underneath.

It's shown for 3 or more lines correctly.

Current Behavior

Scrollbar is not rendered.

Reproduction Steps

var editor = ace.edit("editor3");
editor.setOptions({
    maxLines: 2,
    value: "console.log('hello world')\n".repeat(10),
});

Seems to be intentional, the code is in https://github.com/ajaxorg/ace/blob/master/src/virtual_renderer.js#L1053 and https://github.com/ajaxorg/ace/blob/master/src/virtual_renderer.js#L1081.

It might make sense to only enable the vertical scrollbar but not the horizontal one to still allow the Ace as Input component use case.
