Hi @tnrich this took me a crazy amount of time to figure out, but I finally figured out this display bug:

When a parent element has text-align: center, and a chromatogram in an alignment has trailing spaces, the bars of the chromatogram get centered in the lane, and are not aligned with the sequence:

I made this minimal example to show it in the usual repository, at this branch.

You can try it here: https://ove-playground.netlify.app/

 <div>
            <button
                onClick={handleCenterClick}
            >
                {isCentered ? 'Uncenter' : 'Center Text'}
            </button>
            <div style={{ textAlign: isCentered ? 'center' : 'left' }}>
                <Editor {...{ editorName, ...defaultMainEditorProps, ...extraProp, height: '800' }} />
            </div>
        </div>

I guess the solution should be adding textAlign: left somewhere in the code.
