Initial Investigation

• While a non floated block pull-quote has a class="editor-block-mover is-visible" the block controls display as expected.
• While a pull quote block is floated left or right and has class="editor-block-mover is-visible" the block move controls are hidden. This is caused by an overflow on the parent container.

//editor/style.css line 349
.editor-block-list__layout .editor-block-list__block[data-align="left"] .editor-block-mover, .editor-block-list__layout .editor-block-list__block[data-align="left"] .editor-block-list__block-mobile-toolbar, .editor-block-list__layout .editor-block-list__block[data-align="right"] .editor-block-mover, .editor-block-list__layout .editor-block-list__block[data-align="right"] .editor-block-list__block-mobile-toolbar {
    display: none;
}

Turning off display none will display the block menu controls. However, the controls disappear while visible for the paragraph block that the pull quote is floated around.

You can get the block working properly again by changing left: -30px to `left: 0;'. However, the movement controls will display in an awkward place.

.editor-block-list__block > .editor-block-mover {
    padding-right: 2px;
    // left: -30px;
    left: 0; // moves the block back in the container.
    display: none;
}
