Cover Block height & overflowing problems when used inside a Column Block (6.6.0)

[mrfoxtalbot]

Describe the bug
Adding more than one cover block within the same column block will cause the cover block to overflow vertically outside the parent columns block, overlapping with the content below.

To reproduce
Steps to reproduce the behavior:

1. Create new post.
2. Add Column Block.
3. Insert a two or more Cover Blocks inside the the same column block.
4. The last Cover Block in the column will be way too tall and overflow into the content below.

Expected behavior
I would expect the Cover Block's height to adapt to its content. Instead of this, the block was way too tall and it overlapped with the blocks below.

Screenshots

This is only happening when the plugin is enabled (Version 6.6.0).
The error can be seen on this URL:

If I use with the current WP core version of the editor (5.2) the Cover Block works as expected, here is an example:

Desktop (please complete the following information):

• OS: MacOs 10.13.6
• I initially noticed this bug in Google Chrome Version 76.0.3809.132 but I was able to reproduce it in Firefox and Safari as well.

Additional context

• Version 6.6.0

+1 to this. This overlap basically breaks the ability to use cover blocks inside columns.

The workaround is to add some CSS:

.wp-block-cover {
  height: auto;
}

I've run into two cases of this on dotcom within the past 12 hours.

I also found that this happens when you add one cover block to each column and then add any block below it (instead of second cover block).

For tracking purposes, I came across this issue in 3783115-zen

In my case, I used the following to address a similar issue, along with overlapping text in a different block:

/* Adjust formatting on mobile in Alves to correct alignment and width issues / 3783115-zen pj */
.wp-block-column {
    flex-grow: 1;
    min-width: auto;
    word-break: unset;
}

div.wp-block-cover:nth-child(5)>div:nth-child(2)>p:nth-child(3) {
    line-height: normal !important;
}
/* End - Adjustments to Alves theme to cater for styling issues */
