[Bug Report][4.0.4] v-progress-linear: last chunk not filled when model-value equals max with chunk-count

[valn-ilyo]

Environment

Vuetify Version: 4.0.4
Vue Version: 3.5.31
OS: Windows 10 (current)

Steps to reproduce

1. Render
2. Observe the progress bar — the last (3rd) chunk segment appears unfilled despite model-value === max
3. Resize the browser window a few times — the segment may momentarily correct itself, then break again at certain viewport widths

Expected Behavior

All 3 chunk segments are filled when model-value equals max (300/300 = 100%)

Actual Behavior

Only 2 of 3 chunk segments appear filled. The last segment remains empty despite model-value === max. The bug is viewport-size sensitive — resizing the browser window a few times may reveal or temporarily fix it, confirming it is a pixel/layout calculation race in the chunk boundary rendering rather than a data issue.

Other comments

The bug is viewport-size sensitive. At some widths the last chunk renders correctly; at others it stays empty even though the data is correct (300/300 = 100%). Resizing the container triggers a repaint that occasionally fixes it temporarily, confirming this is a pixel/layout calculation race in the chunk boundary math rather than a data or binding issue.
