Row Expansion causes columns to resize for no reason.

Describe the bug
When the data table is rendered and all columns have plenty of space around child elements, clicking the row to expand it causes the columns to resize unnecessarily. This is a bit jarring for a user. It's also made worse when there are filter and sort icons on the top. This only occurs in certain situations, but I haven't been able to narrow down why.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://icflorescu.github.io/mantine-datatable/examples/expanding-rows/#using-collapse-function-in-row-expansion-content
2. Make sure the browser window is wide enough that all columns have plenty of space.
3. Expand rows and observe column width resizing. *Note that other tables above this example are fine.

Expected behavior
Row expansion should not change column sizes.

Desktop (please complete the following information):

• OS: [e.g. iOS]: Windows 11
• Browser [e.g. chrome, safari]: Firefox
• Version [e.g. 22] 131.0.3

Start by reproducing the issue in the expanding-rows example at the linked demo, using a wide Firefox window and observing column widths before and after expansion. Trace the row-expansion and column-sizing behavior from that example; done means expanding rows no longer changes column sizes, including when filter and sort icons are present.
