Bug

Hello, I noticed a bug in your plugin:
several svg’s in get_toolbar_svg function are malformed, as you can see in the example below, there is one extra quote at the end of path tag.

'resize_font_add' => '<path fill="currentColor" d="M256 200v16c0 4.25-3.75 8-8 8h-56v56c0 4.25-3.75 8-8 8h-16c-4.25 0-8-3.75-8-8v-56h-56c-4.25 0-8-3.75-8-8v-16c0-4.25 3.75-8 8-8h56v-56c0-4.25 3.75-8 8-8h16c4.25 0 8 3.75 8 8v56h56c4.25 0 8 3.75 8 8zM288 208c0-61.75-50.25-112-112-112s-112 50.25-112 112 50.25 112 112 112 112-50.25 112-112zM416 416c0 17.75-14.25 32-32 32-8.5 0-16.75-3.5-22.5-9.5l-85.75-85.5c-29.25 20.25-64.25 31-99.75 31-97.25 0-176-78.75-176-176s78.75-176 176-176 176 78.75 176 176c0 35.5-10.75 70.5-31 99.75l85.75 85.75c5.75 5.75 9.25 14 9.25 22.5z""></path>'
