fix: inline toolbar incorrectly calculates orientation

[SneakiBrina]

Summary

When calculating the inline toolbar orientation, the selection coordinates are being adjusted for the offset of the wrapper element however, the content coordinates are not.

editor.js/src/components/modules/toolbar/inline.ts

Lines 164 to 167 in 77eb320

	const selectionRect = SelectionUtils.rect as DOMRect;
	const wrapperOffset = this.Editor.UI.nodes.wrapper.getBoundingClientRect();
	const newCoords = {
	x: selectionRect.x - wrapperOffset.left,

editor.js/src/components/modules/toolbar/inline.ts

Line 186 in 77eb320

const realRightCoord = newCoords.x + this.width / 2;

editor.js/src/components/modules/toolbar/inline.ts

Line 199 in 77eb320

realRightCoord > this.Editor.UI.contentRect.right

Changes

• take offset into account for comparison against content rects
• added regression test
