Describe the bug
After installing the newest update of the Gutenberg plugin (version 6.4.0) this problem appears:
When editing text in blocks that are further down the page, the window scrolls to the top of the window.
If I disable the Gutenberg plugin and use the stock editor, the problem disappears.
To reproduce
Steps to reproduce the behavior:
Expected behavior
I expect the window scroll position to stay put while I edit the text.
Screenshots

Observe that the window scrolls to the top each time I type a character.
Desktop (please complete the following information):
I am having the same issue. Only way I can type is by deactivating Guttenberg.
Same. Anyone find a workaround?
One solution is to disable Gutenberg and go back to Classic Editor. But I
am accustomed to using the blocks. My next solution is to switch from
Microsoft Edge to Google Chrome. I think it may be a browser issue.

A client has reported this issue, so I've had a look. I confirm - getting this error in Edge, while Chrome & Firefox are both fine.
I reproduced by scrolling down so top of editor is no longer visible.
Then try to edit a paragraph block.
View jumps right to the top of the screen when I type.
However the cursor appears to be where I left it, and if I blindly keep typing, I can see those words when I scroll back down. But typing another letter jumps the view to the top again.
I tested this on a second client site in Edge too, and got the same problem. I don't use Edge as my daily driver, so not sure how common it is or if all sites are affected.
After seeing the error, I updated Gutenberg plugin to latest version (6.5), but this did not fix things.
I'll be advising the client to use a different browser for now, but this seems to be a major issue.
I can confirm this issue is still valid as of 6.5.
Another report in #3416092-hc
every time I type on my blog it shakes.
Edge 18.18362 on Windows 10.0.0
Another such issue reported here: #2392945-zen
I can reproduce the bug in Browserstack. I'll have a look into it now.
The cause is the Typewriter component. I'll see if it can be fixed, otherwise it could be disabled for Edge in the meantime.
The problem is that Edge does not support the y property on a DOMRect: https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect and https://developer.mozilla.org/en-US/docs/Web/API/DOMRect.
I'm surprised not more stuff is broken in Edge because of this. It also doesn't seem to support the DOMRect constructor.
I just had another report of this.
Every time I start typing in a block, it moves to the bottom of the page and I can no longer see what i'm writing
Edge 18.17763 on Windows 10.0.0
This issue is still present on wp 5.3 and Mircosoft Edge, here. Happens on client's computer and in our office. Editing text causes the screen to jump to the top.
Two of my website authors are experiencing this in the latest release too in Edge.
Seeing this on WP 5.3 in Edge (Microsoft Edge 44.18362.449.0, Microsoft EdgeHTML 18.18362)
You are not alone. I can validate this same issue. First time editing a WordPress blog post with a brand new laptop.
The fix will be added to WP 5.3.1. In the meantime you could use the Gutenberg plugin.
The issue is still there in WP 5.4.
