Multiselectdropdown 'select all' option is cut off

[yahiakala]

Describe the bug
The 'select all' and 'deselect all' options are next to each other and getting cut off in the dropdown. I have tried to have the width set to 'auto' and 'fit' and having the same problem.

Version
Published app - using the App ID as a dependency.

To Reproduce
Steps to reproduce the behaviour (including a clone link when applicable):

1. Add a multi-select drop down to a form
2. Populate it with a bunch of options
3. Select 'enable_select_all'

Expected behavior
The width of the dropdown should be wider than the text.

Screenshots

I am considering making a PR for this issue
No. I have disabled 'enable_select_all' to deal with this issue.

Could you provide a minimal example clone link
Following those instructions doesn't show the issue for me
I suspect it's something to do with some css

Here's a minimal example: https://anvil.works/build#clone:XSS33QAN6IQ5IF6L=EAD7VSTHC2JT4DLGG6HRREUZ

Basically, 'auto' and 'fit' are not taking into account the width that is required for the 'select all' and 'deselect all' buttons. If the options are less wide, the dropdown will be less wide.
