[Bug]: External storage "Restrict to" multi-select does not grow with selected entries, chips overlap the next field

从外部存储设置界面开始，追踪“Restrict to”多选框及其布局，然后检查 @nextcloud/vue 9.10.0 / 9.11.0 中引用的 NcSelect 溢出修复，以及相关 issue #60720 和 #36697。在编辑对话框中添加多个用户/组来复现；当字段变大或可滚动，且其中的标签不再与下一个字段重叠时，即为完成。

⚠️ This issue respects the following points: ⚠️

• This is not a troubleshooting question, general support matter, or webserver/proxy problem, but likely a bug (if unsure, ask the Community Help Forum).
• This issue is not already reported on Github OR solved at the Community Help Forum (I've searched!).
• I'm using a maintained major version of Nextcloud Server and tested against the latest patch level. (Supported major versions and current patch levels).
• I agree to follow Nextcloud's Code of Conduct.
• I've tried my best to provide clear reproduction steps that someone unfamiliar with this bug could use to reproduce it.

Bug description

In Administration settings → External storage, in the "Edit storage" dialog, the "Restrict to" multi-select does not expand vertically when several users/groups are selected. The selected entries (chips) overflow the field and are drawn on top of the next field (the "External storage" backend select).

Browser zoom does not change the behaviour.
Reproduced on two different rendering engines (Firefox/Gecko and Brave/Chromium), so it does not look browser-specific.
The font in use is Inter, as expected.

Steps to reproduce

Go to Administration settings → External storage
Edit an existing mount (SFTP backend in my case)
In "Restrict to", add several entries (1 group + 4 users here)
The last chips overflow the field and overlap the "External storage" select below

Expected behavior

The "Restrict to" field grows to fit its entries (or becomes scrollable) and does not overlap other fields of the dialog.
